Trazodone not effective; may as well try Ambien, but maybe half a tab at first.
Consider your own physique and reactions to alcohol, etc.
When I was a flyweight (95#), I was a very cheap drunk. I can put away a bit more now.

After my knee surgery (motorcycle accident), the post-op "hypos" had me bouncing off the ceiling.
I always do best with minimal medication.
I had an rx for alprazolam, but an entire pill left me hung over, so I split them all.
Years later, I still have a tiny stash of crumbs--just in case . . .
