My doctor has determined my serotonin is off again and it makes me jittery inside. I hate the feeling. I have lost 10 lbs since Feb. she said and I know if I go back on a serotonin SSRI med like Lexapro here comes the weight gain. But I would rather be fat than have times of nervousness. My IBS-C affects it also. I tried Wellbutrin and liked it.IT made me calm and didn't shut down my emotions like Lexapro does but I had a bad experience with the 300 mg that lasts all day. So right now I have started the 5mg of Lexapro generic to see if that will boost it enough to help me.

When my doctor put me on it back in 2002 he was the first one that told me about serotonin. I was a nervous wreck and thought I was going to have a break down. I told him I didn't understand because I had a wonderful life and husband. So he gave me a VHS back then to watch about it. Then he put me on it and after a time I was very surprised at how I felt. In weighed 96lbs and could not gain weight.
