Best sleep medication for staying asleep?

I'm on gabapentin again and I have never been sleepy with it

I just took doxylamine succinate and had the hardest time with it. I took a tylenol pm and no sleep. I am so frustrated. I took 2 tylenol pm and slept amazing last night. But before that 5 days of no sleep.. help

600 mg of Seroquel

Gabapentin

Costco sell it but doxylamine succinate is one of the best meds I ever tried for sleep. And I HATE taking meds. It’s pretty much overdose proof. However it can make you still feel drowsy when yo I first take it so try to give yourself like 10-9 hours before you have to be up until you see how it affects you. It’s non habit forming but you can build a tolerance so dont take it too often.
