Citalopram
"[24M} I was prescribed 10mg/day of citalopram, increasing to 20mg after that for anxiety. I only made it 4 days before I couldn't stand the side effects and had to quit taking it. Drowsiness, erratic sleep, weird dreams, nausea, headache, extreme thirst and dry mouth/lips, lack of coordination and dizziness. The worst side effect was that it completely killed my sex drive. I don't think I was on the drug long enough to see much benefit, it did seem to calm me down, but some of the side effects made my anxiety worse."
