If you don't have insurance perhaps there's a local state-funded detox? I know in Florida we have one for Broward County residents. And it's not ideal, but the EMTALA is a federal law which requires all US hospital ERs to admit and stabilize anyone seeking emergency care regardless of ability to pay. I myself have done a few hospital detoxes, and while they weren't exactly comfortable, they kept me alive

And finally as a last resort, you can try detoxing yourself by weaning off alcohol. It's extremely hard to do and requires a ton of self-discipline and it will be very uncomfortable, but I have managed to do it successfully a handful of times. I should say tho that for every 1 time I was able to detox myself, there were probably about 5 times that I failed
