Hyperthyoidism itself can lead to the fatigue. But I know I felt better when I split my doses throughout the day. I was getting relief when I took my dose and then it wore off and I would get the crazy hyper symptoms all over again. Splitting the doses stretched it out over the day. If you felt better on your prior dose and feel worse with the new dosing, talk to your doc about his/her suggestions.

Hope you feel better soon!

I take 1/2 around 6 in the morning then the other 1/2 at 6pm.
I do know that I was getting very tired in the morning taking the 5mg in the morning. It seems to hit at the same time every morning. 9:00 - 9:30.
Maybe just overly worse today and it made me a bit 'nutty'.
This is new to me so I'm still adjusting to what I am dealing with.
Thanks for your answer! I'm reading and re-reading these posts and do find myself having many of the same issues.
It gets a bit overwhelming at times!!

I really cant comment on meds without lab results. Have you had one recently? Are you due for another? If you have them please post lab results along with the ranges. This site has problems so if you post it like this you should have no problem. TSH 1.2 range .03 - 3.0

I would really consider cutting out all junk food altogether. We have some excellent threads going right now about diet. Splitting your med doses can only help you feel better...unless your under/over medicated. Big Hugs...Kathy

Right, if you are over medicated you will feel tired after a dose cause you're already hypo from it. That's how it affected me too when I was overdosed. Although if you just started on the meds and you were really hyper you wouldn't feel that tired but some do when hyper, it's more like tired from not sleeping though. How do you sleep, do you have a hard time falling asleep at night? We would need to know what your labs are to see where you are in the ranges.

Thanks Kathy and Bransana!
Here are latest labs (I checked the T3Free box on my own)

TSH .007 range is.450-4.50
AST 13 range 0-40
ALT 11 range 0-40
T3 152 range 71-180
T3 Free 4.0 range 2.0 - 4.4
T4 Free (Thyroxine) 1.18 range .082 - 1.77

That was from mid-June. I'm having next lab the 7/6 and will post those.

I do have problems falling asleep at night. Funny thing is I can come home from work and fall asleep with no problem.
I'll try harder with the junk food. I was living on chips and chocolate during the day for a few months before diagnosed. Lost weight on that diet!
I have had panic attacks since my early 30's that scared the crap out of me. My family doctor said it was all in my head. Nice.
Slipped on ice and broke my femur on 2/2/2010. Heart rate went up past 150 after that. Prior to surgery, the hospital did heart echo and stress test. Heart is fine and that's when they ordered the thyroid blood work. I had a hard time comprehending Hyperthyroidism/Graves.
For 8-10 months before breaking my leg, I was having very high heart rates and things just didn't feel right. I'm very glad to know it's 'something' and not in my head!
Thanks again.

It seems that maybe 5 mgs may be too much for you, eventually. If you stay on this dose and your next labs find you more toward hypo, then you need less. Your FT4 is at 1.18. You don't want it much lower than that or you will be tired feeling for sure, especially if you are younger. Your FT3 is in range but is taking a little longer to come down. I think labs look good as long as you don't fall lower with the FT4. The beta blocker will keep the FT3 down.(good for you checking it off!) It sounds like your diet was contributing to the racy feeling too.

I just went through some 'dizzy' spells like someone else had descibed. Not passing out but feeling like something was pushing me down. This passed after I was freaking out and took a 1/2 metoprolol. First prescribed it taking 50 mg morning and night, then once, then half... blah blah..!!
I just don't understand the 3 and 4 numbers and what they do. Also the TSH at .007. My daughter talked with another Endo at a friend's house and told her about what I was going through. Her answer was RAI. She's younger than my Endo, who she knows, and called him weird. Yes, he's odd but he's leaning towards RAI as well. I'm 58 and it seems the symptoms have gotten more pronounced since menopause a few years ago. By the way, menopause was wonderful! No more periods!! As I posted before, I had panic attacks in my 30's and my doctor said it was in my head. Grrr.
I do understand that diet can affect the way I feel. After the way I felt today, I don't want to eat anything again. You know? Sorry! I need to whine a bit. I'm tired of thinking that each thing I eat will cause heart palps and feeling 'out there'.
Sorry again, I've been dealing with a lot lately. I know stress can cause quite a lot of strange feelings. I know that I cry at the drop of a hat. I have always been one to cry when I'm mad or happy!

Thanks so much for answering me!
Marsha

One more thing... I went back to taking 5 mg Methimazole two days ago in the morning and didn't feel tired all day.
ACK!! I'm so confused!!!

Remember, there are lots of things that can make you tired- morons next door with firecrackers, to start with! (We've had that at my house, too. I hope they've run out already.) Cutting down on caffeine could have something to do with it, as could changing your metoprolol. Being tired for one day, or one morning, may not have anything to do with your thyroid at all. Being tired for several days, with no explanation, may. A high heart rate is more directly related to your thyroid.

Thanks altoclef.
I'm trying to read as much as I can to get on the right page! Every time something odd happens I kind of freak out.
I cut out black high test coffee and only drink black de-caf now. I knew that would affect me as I could have gone through an entire pot.
I'm going either today or tomorrow for bloodwork and should have results by the end of the week.
I will post those again to compare.
Thanks again
Marsha

Did you have your antibodies checked to see if you really have Graves? (the TSI test) If you need a small dose of 5 or lower, you don't need RAI. That's for some who can't get adjusted on meds after months and months.(usually it's the doc's fault) I looked at your profile. You are an older gal, you will probably go hypo in time naturally, don't fall for the RAI, usually people feel worse after this treatment and it would take a really good endo to set you straight again. They just like to make us hypo so they don't have to worry about us anymore.

Thanks bransnana.
Gee, I don't feel old!! I'm having bloodwork tomorrow and will post this. I'm trying to educate myself before calling my Endo in August.
(Wish I could have a month vacation!)
Maybe I'm looking at the size of that little pill wondering how 1/2 a pill could be over-medicating. I guess I just don't understand the power in that little pill.

Thanks to you and everyone for your help.
Marsha

Yes it's true, the Methimazole is a powerful pill. Stronger than ptu. If that's the dose you need then that's it, don't worry about it. I took a quarter of a 5 mg pill for months and months, took that little pil every day,then 3 times a week, then 2, it was enough to make me hypo, had to get off completely. I don't mean you're OLD just older than some on here. I'm 55 so I'm there too! We "older"ones seem to go hypo in time. Don't need RAI. The older you get the more your thyroid is apt to sputter out,especially if you've been on the meds awhile, we eventually need replacement. Not always though, sometimes there's a brief period of hypo after off the meds then back to normal.

Hopefully my Endo will see the light !
I just started all this stuff in February.
What a ride!
