Has anyone been suffering with post Covid severe insomnia?

I, too, am one who cannot take antihistamines for sleep. I get hyped up instead of sleepy. The only thing I have found that helps me now that I had to taper off Klonopin is a CBD/THC gummy and it does not always help. Yet my neighbor finds good relief with Unisom and says the gummy does nothing. We are all different, yes!
