Hi ttm
I suffer from chronic pain too and I've used both weed and alcohol unsuccessfully in the past.
The best thing I think to do is see a Pain Management Dr.
There's a whole range of pain relief available these days that isn't addictive...you may even find there are non medication ways to help.
Be honest about your addictive past, and a good Dr should find the right non addictive but effective pain relief treatment for you.
Good on you for giving up the weed btw - keep posting here for support
