My son’s a heroin addict, and when he comes off is just as difficult (maybe more so) than when he’s using. He suffers from PAWS which makes him irritable and very bleak. You kind of think it’s going to get easier when they come off but it doesn’t. Also my son medicates with other things to help with insomnia and anxiety, so I have no idea what’s going on. Heroin addicts are very secretive and when they relapse it can take a while to find out, you probably no all of this. You end up feeling like your going mad. I wish I could advise you what to do, but it’s a long hard slog for both of you. You can get really good support from Drugsfam, they have a helpline, if nothing else they’ll help you to think about boundaries and make you feel less isolated. Heroin is an absolute curse, I really feel for you xxx
