What helps you stay asleep throughout the night?

This is gonna be a rant/question. So for 6 years I’ve been on sleeping and a few months ago I quit taking them. I used to take 2 then went down to 1 then a half and no matter how much I would take I would be too tired throughout the day. It was going good for a little not taking the pills falling and staying asleep. Now I’m back to waking up throughout the night, can’t fall back asleep after and having my heart race so bad that it makes it hard to breathe bc I’m so bothered by not sleeping. It’s messing with me mentally I’m drained I cry when I don’t sleep well. So what do you/take to get 7-8 hours of sleep a night and not wake up? Thanks
