I read most of the posts really often and all of you help so much by sharing what helps some of you. Sitting at the computer very long is painful, so I don't post very often. Changing my diet lately to a small amount of fruit, veggies, and small amounts of chicken seem to make a world of difference in how I feel. What bothers me most is chronic constipation and colon pain. I take threelac and other probiotics. I tried Provigil today for the first time, 100 mg. this morning, and really enjoyed the extra little energy boost and being able to focus better, but, I have had palpitations a lot today. Palpitations have always been a bit of a problem for me, but, today was worse. Could this be the provigil and will it get better? Thanks to all of you for being on this message board. You have done more for me and how I feel than any doctor over the past 19 years.
