I began taking Zoloft 12.5mg roughly 4 weeks ago, although I feel as if it has helped my panic attacks, depression, and anxiety the insomnia is horrible. I barely sleep if any at all. I also take a .5mg Xanax in order to try and get some sleep and if I do, I'm lucky to get an hour. I have issues falling asleep and then staying asleep. I take my Zoloft at 5pm every day. Is there any hope of sleeping again? I have heart issues and if I don't rest good my heart acts up on me something awful... help please!!!
