I really understand how you are feeling. I got insomnia out of the blue last April (2 years into peri) which may have been triggered by a huge family bust up some months earlier. I had 3 days when I couldn't sleep at all then I paniced about it (don't Google Insomnia!) and got into a cycle. Be reassured it WILL get better, I am sure it is hormone / stress related and your body WILL get back to a more normal cycle. Two things helped me. I found a great GP who said the first thing is to get a good sleep to get out of the cycle. I tried ' Z' tablets (Zopiclone) but they didn't work then Nitrazapan. (I am not keep on sleeping tablets but am glad I took them as after that 8 hours I felt a different person). I only took them for 2 weeks and during this gradually tapered them down to zero. I also changed our bedroom; blackout blinds, move the bed to darker spot, new bedding, painted the walls mushroom (were magnolia) and got ear plugs. I got an alarm clock that has a faint buzz as background noise. My GP said not to stay in bed and stew about not sleeping so I try and make myself get up after 30 mins and do some stretching. Best tip was when you get in bed to not shut yr eyes; just stare at the blackness for 15 minutes and tell yourself you are not allowed to go to sleep; this more than anything makes me sleepy. It will pass though, try not to worry. Have a chat to a sympathetic GP; there are ' sleep schools' around the country you can be refered to.
