"i began taking paxil in addition to celexa two years ago when i was 16. it is not bad--no stomach aches, weight gain, or horrible headaches--but i have noticed the total disappearance of my sex drive. totally gone. this might be because of the celexa as well. not sure. i was taking 40mg celexa, 20mg paxil, 1 mg ativan, and occasionally trazodone or doxepine to sleep, for a while and when i cut my dosage in half over the summer, i was a mess. constant migraines and irritability. so i suggest that if you use paxil, be careful to come off it slowly."
