Oh I’ve not heard about GP’s having weekly appointments arranged, either way that’s pretty impressive. Usually that would be the drug and alcohol services that check in weekly, or perhaps social prescribing. Sounds as though he is dipping his toes in water which is a good sign.
All the things he said he enjoys, coke and girls etc are all superficial and that’s a neverending pit. Be careful you could still get hurt in all this! It’s probably going to be a long road ahead.
