I've had this issue since peri-menopause. For me it's a combination of several things. Low blood sugar, fluctuating hormone levels and any number of other things, including too much salt. I've tried the warm milk and turkey before bed. That doesn't work. I need a high protein diet. So I have some before I go to bed. I refuse to take drugs for it. They cause more problems than they solve, and I hate feeling drugged up. Smoking pot doesn't help....tried that. It's legal in my state. I don't drink. It's incompatible with my bp medication. Twenty years after menopause I still have hormone cycles, of all the ridiculous things. Some nights I sleep better than others, but at the most I get 6 hours sleep. Some night's it's two. I meditate. I exercise, so that every thing keeps working. Any ideas?
