I know this will sound strange but I think I accidentally discovered a treatment for my inability to get back to sleep when I wake up in the middle of the night. Like a lot of people my age sleeping straight thru the night became a rare occurrence. Recently I read about spinach powder helping to control your appetite so I bought some. It tastes really disgusting so I mixed a spoonful in a glass of orange juice and held my nose while drinking it. That night I slept through the night without waking up. I drank this concoction for a couple of days and continued to sleep well. Sometimes I would wake up but I fell back asleep immediately. I stopped drinking the concoction because I got busy and didn't think about it and within a day or two my night time waking issue returned. I started drinking the disgusting concoction and once again I started sleeping through the night. I don't know if this is just a fluke but it's working for me.
