Hello Doctor, I m 73, a woman, a retired Ph.D. from biomedical research. My insomenia began around when I was 70. Now I go to bad 11pm, but would wake up every half or an hour for several times: during my wake up, I feel legs tingling which makes me turning and turning and can t stay in bed ( I hate this tingling feeling), so I have to get up to do something, and then go back to bed, trying to sleep again. I have to repeat this round trip several times every night until 2-3 am, then I can sleep for 2-3 hours, wake up, and then go back to sleep for another 2 hours or so until 8-9 am to get up. (If I get up early, then the day will be ruined.)
Hi, I had gone through your question and understand your concerns. You probably suffer from Restless Legs Syn Chat Doctor.  This condition in most people hasn't known underlying etiology (disease), but in few cases' neuropathy may cause it. I suggest you to consult a Neurologist and discuss further steps in diagnosis and treatment of your concerns. Hope this helps. If you have further questions feel free to ask.
