I started taking Trazadone, 100mg a week ago and it only worked the first night and a little bit the next 2 nights. And bizarre dreams. It doesn't work anymore but I keep trying, then one night it worked but I had an anxiety attack right before I fell asleep. I heard you can safely take up to 200mg. Has anyone done this or 150mg dosages. If so, did it help you? I'm becoming "sleepless" again and I hate it! Help
