Dear Dennis,
I know of your pain. I evolved into chronic insomnia after getting tinnitus in both ears. I couldn’t sleep. After 2 1/2 months I was forced to retire. I was on some of the drugs you are in. Have you tried Magnesium Glycinate, Magnesium Threonate, and/or glycine. These are natural supplements that can be helpful for sleep. I would start with the Mag Glycinate 60 mins. Before bed. I take 480 mg. If you wake up in the middle of the night try the Mag Threonate plus Glycine. I would also speak with someone who specializes in CBTI , chronically therapy for insomnia. I don’t completely trust the psychiatrist or neurologist, they are good at passing out pills, but don’t always get to the main issue. Right now you need to stabilize your sleep as much as possible.
