Sorry, I have not had this so I am not much help. My sister did and I think they did something called coasting where they took her off her drugs to see if it would settle down. Also, I posted a website yesterday with IVF tips and this was one of them:

Some clinics believe that a diet that is high in protein and low in salt and potassium can help you avoid hyperstimulation. Gatorade is a poor choice of fluid to drink to prevent/control hyperstimulation because it contains large quantities of salt. Water or Pedialyte is best, in quantities recommended by your RE. At a certain stage of OHSS, too much fluid can be detrimental.

My sister ended up pregnant and now has a baby boy. Good luck!

I just got over slight hyperstimulation, and the only thing that can really prevent it would be to not trigger ovulation, which my RE advised me not to do (but I did anyway!) . My symptoms weren't too bad, to be honest - the RE just had me take it easy, i.e., no strenuous activity, no heavy lifting, etc. I had to watch for a weight gain of over 5 pounds per day.
Good luck to you!

I had hyper stimulation. The re wasn't sure if she should do the IUI, but I decided yes, at this point I just want to get pregnant - none of them took so she worried the heck out of me for nothing.
I felt fine the day of the IUI, but the next day my ovaries felt very heavy - it was a very weird feeling (but she did warn me of this). I had to go back every other day to get my measurements taken, blood work and she kept checking my weight.

i'm getting my u/s tomorrow so i'll let you know...but how do you feel right now physically?

also-what were the dosages you used? i had 125 for 2 days, then she called after checking my estrogen level-and i dropped to 75 yesterday and 75 today...

let me know what your levels were..

staydes-
I was taking 200iu of follistim. Yes definately let me know how your appt goes.

I have hyperstimulated three times. All three were pretty bad. There isn't anything you can do to prevent it. The shot you take to make your eggs drop maked it worse. The bright side of all of this is that you are at least able to produce follicles from this. Please let me know if you have more questions (how it feels, how you can tell you are getting it etc) I will be happy to help!
