Help getting off Diluadid

Hey so I’m a long time user have been in and out of recovery over the years. About 3 months ago I started seeing a Dr managed to get him to prescribe me 15 D8’s a day (it’s the safe supply program I’m in Canada) which I’ve been IV injecting and then started mixing with C@ke. Bad combo obviously so I’m back from a 4 day stint in detox off the C@ke, but I can’t get myself to come off the Dillies. My girlfriend and my ex, the mother of my child are on my case about it and I get it. As much as I don’t want to admit it, yeah I nod out, I haven’t worked since July. I totaled my car in September cause I fell asleep at the wheel. But I still feel like I’m in pain, and I need them. However if I keep going like this I’ll lose everything including seeing my daughter who I love and an amazing woman who has stood by me through so much. So what do I need to do-other than quitting cold turkey. How can I get off of these the quickest and with the least withdrawal?
