Have you tried Trazodone? It's an anti-depressant with a side effect of sleepiness that's commonly prescribed for insomnia.. I started having severe insomnia a few years ago and that was the first medication my Dr prescribed. I don't want to take any heavy-duty meds where you can sleepwalk and not remember your actions. Right. now I take 200mg Magnesium Glycinate about 2 hrs before bed. I take a CBN/THC sleep gummy shortly before bed, and 2mg melatonin and 50mg Trazodone about 15 minutes before bed. Combined, they make me sleepy. The trouble for me is that I wake up about 4 hrs later and have trouble falling back asleep.
