Your fear is interfering with your sleep. I am a vietnam Vet. I have ptsd and take 2mg of melatoni, 10 mg of mirtizapine and recently 10 mg delta 8 and CBG 10 mg in the form of gummie. That last one is soooo great!
When I take the gummie I fall asleep very naturally and wake with no after effects. It is to the point that I am considering to eliminate the mirtizapine. Look at it this way ,you have receptors for the delta 8 and 9 and the cbd's. otherwise none would work!It is as 'natural" as can be. I tried the indica delta. 9 with cbn and had a 'hangover" in the morning. Nothing too baud but noticeable. The delta 8 and cbg has no hangover at least for me.
The mirtizapine does diminish the restorative phase of sleep and that's a reason I want to stop it.
