I tried 100 times too and finally have been successful the past 3 months. I feel so good at age 71 now that I am off most medications but especially off Valium, which I took for years for insomnia. Keep trying. Success is worth it. I used Ashton manual method. Find something that works for you.
I don't sleep well. I no longer sleep in the same room/bed with my husband because he is a sound sleeper and has never had problems sleeping. I have had problems sleeping since childhood. If it is possible, sleep in separate rooms so you do not disturb your partner, but only if she is okay with it. I am sure she loves you! My husband was not okay with the idea of sleeping separately, but I insisted for both our well-beings. He has accepted sleeping separate but has never liked it. It is not a topic most talk about but when it has come up with other couples, I was very surprised how many couples no longer sleep in the same room. We have been sleeping in separate rooms for 5 years now. I have to get up several times a night, read or physically do something, and then I go back to sleep. I rarely nap. Best wishes.
