Hi Amy. Thanks. So far, the only side effects I have had are dry mouth and not being able to eat very much. Over the weekend, I had to force myself to eat and I can only eat just a little bit at each meal. What scares me about this is that I am taking 150 milligrams a day right now and on Wednesday, I will be taking 300 milligrams a day. I hope this doesn't affect my eating even more. Have you had this problem?
