I too have anxiety, Sleep insomnia. I was diagnosed a year and a half with a heart condition that required a pacemaker defibrillator, which intern helped me dramatically, but my mental state concerning this gave me severe anxiety. I am good now feel much better physically, however, the sleeping insomnia began the worrying at night. It’s been a year since this started I don’t really think I worry about my heart anymore. I have used every over-the-counter supplement over the last year some of which worked for a while and then stopped. I also began with the muscle twitches starting in my eye lid, then my arm and my thigh and my calf all over my body. I was twitching for several weeks, which was very frightening. I finally went to my primary doctor with all my symptoms, and he gave me Ativan to sleep at night, but I did not want to get dependent on a benzo. So then after more sleepless nights. my doctor prescribed me Q Vivek, which was almost like a miracle from day one for three full months I would fall asleep within a half hour after taking it and sleep seven hours through the night wake up refreshed without any side effects. Suddenly after three months, I would have a sleepless night here and there with the quviviq then suddenly stopped working completely. I was so disappointed so back to the doctor I go. I have been given another new sleep medication for anxiety and sleep, which I just started three nights ago. I do not seem to be getting much help with it yet so last week I decided to research the online program CBT – I. I just started it a week ago and just began sleep compression three nights ago which I have found to be very difficult but I’m going to try to hang in there at this point I am getting approximately 4 hours sleep.
