Don't know if this is going to be a popular suggestion or not but when I read about the caffeine, I really heard you on that one. I have a HORRIBLE time giving up caffeine, the induction flu is NOTHING compared to the effects of laying off the caffeine for me. My gut is telling me that this may be making the headaches worse for you. As a result, I have never stopped the coffee during this WOE. A lot of other people continue to drink it as well and loose fine. Perhaps you could either slowly wean yourself off, just cut down or not quit at all? Maybe quitting everything at one time is a lot for your body right now?

Also, your workouts on top of everything else-- that may be totally pushing you over the edge. I agree with the other poster that suggested you check out the general exercise forum. You may just need to add something to your diet to compensate for your workouts too.

Hope you are feeling better very soon!
