@padovani- Unfortunately many sleep meds are very addictive. Have you considered taking a long term anti-depressant during the day? I will last all day into the next when you take your next one. Xanax might be wearing off after 4 hours. Sleep habits are difficult to break. I know when I don't get very steady sleep I'm a mess. Without sleep any other problems are exaggerated.

Good sleep habits are very important: https://www.sleepfoundation.org/sleep-tools-tips/healthy-sleep-tips

Has anything happened to set this off? Do you have any other problems that can be causing this? Have you spoken to your doctor about it?

I don't know if this works for others..... but before I would wake up at every little sound and then lay there wondering if someone was in the house or what the heck was going on so would end up losing hours of sleep. Since I have an echo I decided to put on some meditation music at nite when I go to bed and now I sleep thru, don't hear those noises, don't lay away thinking but sleep very soundly. It helps me to relax. Not saying its a cure but it helps me...…..Best wishes to you Padovani
