I have heard about the dehydration as part of dm. In my support group meetings people have talked about being more easily dehydrated. Drinking alcohol is probably not such a grand idea- it can mess with meds and such, but i think u were just joking bout that. some where it does say how certain stuff in red wine helps reduce inflammation. I guess moderation might be key.

I think you're meaning "resveratrol." Not sure, however.

I only have PM. I describe my headaches the same way, LOL!! Even though I drink at least 10 glasses of water a day, I always feel dehydrated in the morning. Almost everyday I wake up with the headache but it goes away once I drink 2 glasses of water and eat my breakfast and take my Pred. and supplements.
I get the headaches on the weekends also, but they seem to last longer, sometimes through the weekend. I take my MTX Saturday evening before bed and I think that is why they are worse.

Luckybabe, I had such a bad headache last Tuesday night, that I threw up five times. My doctor told me the next time my headache gets that bad, I should call 911. I know what you mean about headaches. I do get dehydrated. I drink a lot of water daily and at night. I can not drink wine because I take methotrexate. I get dizzy and the dehydrated feelings a lot. I can relate to what you are saying. I just think it is the medication. Gatoraid helps well with dehydration too.

I don't know if I am dehydrated but I do drink lots of water and feel thirsty often. I get headaches from my Methotrexate from time to time. The only thing I've found that works is Excedrin. It works better than anything else I have tried including prescription medications.

I hope you find some relief. Headaches are never fun.

Thank you everyone for your kind replies, advice and hints!
