Hello, I am really feeling lost and helpless right now.  I started taking 25 mg of zoloft for my anxiety and it's been one week and I have experienced the worst insomnia.  I haven't slept in 4 days and I've tried taking zzzquil or xanax, none of which helped.  I asked my doctor for ambien, but she doesn't want to prescribe those to me, and instead wants me to switch to a different antidepressant called trazodone.  has anyone ever taken trazodone before?  i'm not sure whether to switch to trazodone or continue taking zoloft and see if it gets better.  help!
