I was on it for about 18 months, after a sudden bereavement and work was horrendous. I was worried about side effects but aside from really vivid dreams, they didnt affect me too much when I started out on them. I didnt seem to benefit very much from them, and although I dont know what I expected, I now feel no different without them. The Doctor told me I was depressed, they gave me Sertraline and sent me on a stress management group
I hope they work for you- I know some people have really benefitted from antidepressants.
I came off them after speaking to ky GP - they just said reduce the dose but they didn't seem really sure
Be warned tho - the 'brain zaps' when you come off them, I cant quite explain them, but they're wierd and a little unsettling, but apparently its completely normal. I also had the dizziness. Good luck
