I have been on Zoloft for 3 months now and feel too like it has changed my life. I take 25 mg a day, and no longer get nervous in groups of people or dread social situations. I'm also a lot nicer to my husband! I used to worry about EVERYTHING, but now I don't let things get me down. It's great. I can, however, feel some "twitching" (for lack of a better term) going on in my brain which makes me think about brain aneurysms. I"m curious about the long term effects of Zoloft use on the brain. Does anyone know?
