i was diagnosed with sleep insomnia, ptsd, panic disorder, and major depresive disorder a little over a yr. ago. at first, the dr's just had me on a low dose of zoloft to see if it would help. tho it did help with the depression and a little with the anxiety, i still couldn't sleep. after raising the dose of my zoloft a few more times, and trying seroquil, the dr's finally put me on ambien when i couldn't sleep.
