Tips for sleeping after quitting?

I quit last February but since the summer I’ve been smoking before bed again. I can’t stand the brain fog I know it’s giving me and having little to no motivation everyday. When I quit the first time it was so easy because it was worsening my already pretty bad anxiety at the time. Now though, it’s like every night I have a draw to smoke. Without it it takes me a while to fall asleep , my eyes will feel heavy but the rest of my body and mind feels restless. Maybe that’s just normal and I don’t know because I’m used to being knocked out cold for the last 6 years

Ive tried a few things but still find myself reaching for my bowl every night and not going to bed until 1AM. What has helped you guys with settling in at night and being able to fall asleep at a reasonable time since quitting? Thank you in advance
