As a long-time insomnia sufferer, the anxiety of not being able to get to sleep is always something that keeps me up.

Get up. If you wake up and feel anxious or too alert to go back to sleep, don't try to stay in bed. Get up, take a shower, dry off, do some stretching, and then give it another try.

I don;t know what state you live in, but some cannabis gummies are great for sleeping.

I don't usually recommend an antihistamine because of the hangover, but taking a half or quarter dose of liquid nyquil (Not zzzquil) and go to bed several hours early.
