My doc just changed me from Celexa to Zoloft because I have had anxiety pretty bad lately. He also gave me Xanax. I have been taking ambien at night for a few years now but still only sleep about 4 hours. When I read up on Zoloft, it said that it helps people with hypersomnia but it also says it helps with insomnia so I don't know if I should take it in the mornings or at night. I have both. I can't sleep and I don't feel like doing anything during the day. I have chronic depression, by the way.
