hey there...
I understand what you are going through....i busted my neck C1 and C2 back 2 years ago...had been clean and sober for 2 years.....was put on morphine in the hospital and a neck brace.....fast forward 3 months taking huge cwe solutions of codeine once the scripts ofr my pain killers ran out...former meth head, opid addict and alcoholic.....this went on for 2 years....recently completed rehab....my partner and kids put up with it for 2 years...i got sick enough to want help......despite his injuries he sounds bad and needs help...he can do it.....you dont need to live with that crap anymore and you both deserve better...
get him to a detox and rehab.....
best of luck v
