I know what you are going thru. I literally freak out if I'm not sleeping well because I am so scared of the worst happening. I've been I think on everything you have been and unfortunately the only pill that works for me is 400mg of Seroquel, and sometimes that doesn't even work. I have trouble getting to sleep and staying asleep, my mind never shuts up. The past few nights on top of my seroquel, Xanax, and Propranolol I had to pop 3 benadryls. I had a sleep study and nothing is wrong. I hope you find relief soon.
