Sorry to hear of your long battle with sleep issues. Although I used to have insomnia during my first year of recovery I mostly have overcome this. However, for 1-3 days after doing too much or being overstimulated, I have great difficulty, despite being tired, falling asleep... it feels as if my brain is stuck in an "on" position.

Anyway, of all the things I've tried, a THC-oil has been the best help for getting and remaining asleep. I take it at 9 pm-ish and usually am asleep by 11ish. Unlike melatonin, the THC helps keep me asleep for most of the night. One down-side, though, is that if you need to get up for a pee, you are VERY drowsy. Worse, for me, I have great difficulty actually peeing despite having a painfully full bladder... lol. I actually have concerns about falling asleep while trying to pee... almost happened a few times.

Might be an option for you to help get past your insomnia.
