I have the same problem. It can take me hours to fall asleep and that only if I take some antianxiety medication, like Xanax. I am so tired I literally fall asleep at work at the desc but at night even though I am soooo tired I can not fall asleep. I also tried melatonin, and nothing. I am very interested in answers here. For me, only benzos work but I know it's not solution just pathway to addiction.
