I was on 40mg of citalopram which reduced over a month and just started sertraline on Friday. I feel awful! I did when I started citalopram but in a different way, now I feel like I've got a funny kind of flu, I'm dizzy and throwing up. I know it can take a long time to 'properly' work but is there hope of feeling any better anytime soon? I called in sick today and work were awful which doesn't help. Eek
