I would suggest that the best person to call is the AA helpline, it will be manned. Better than anyone here for these reasons 1, they are actually sitting there waiting for such a call - they want to help and have volunteered to do so - at whatever time you call, 2, they will either be local to you, or will put you in touch with someone local to you.

I did this after I relapsed, spoke to someone on the phone, and the next day 2 guys came to my flat. OK it took me quite some time to get lasting sobriety again but the phone call was the start of it. 2 years later I still see those guys around - reminds me where I was.

Call them - it’s your best move
