Thing is, it might make you pass out - but the sleep you get is not the restful REM sleep.
Tough it out for a few days/couple weeks and your sleep will become restorative again. It's going to be uncomfortable and your sleep will be erratic for a couple weeks, but it's worth it.
I used to come here in the middle of the night when I couldn't sleep in early days. Usually I would have some milk and toast and was able to go back to sleep. Often it was nothing more than early sobriety jitters and blood sugar dips.
I don't lie in bed ruminating, that's a recipe for fear and self-loathing in early days. There is always something to read here...and someone to talk to. When I couldn't sleep, I got out of bed.
