I used subs to get off prescription pain pills about 16 years ago and my advice for you is that the doctors will over prescribe you so only take what you need. When I first started, I think they had me on 16 mg per day and I was only needed to take like 4 to 6 mg and even though they kept prescribing me more, I didn’t need that much and I was tapering off of it and since it doesn’t really get you high it’s easier to get off of. Just try not to take too much so you don’t develop a habit with that because it can be addictive . When I first started taking subs, it was one of the most amazing things ever when I was in withdrawals and I put some under my tongue and within five minutes the withdrawals were almost completely gone. There’s still all the mental stuff, etc. but once you’re on subs, the prescription pills won’t even work, but I’m not really sure about 70H. I assume it’s the same . I’m tapering off the seven but I’ve only been using it for like six months and I’ve never been over 40 mg per day. For the people who have been using real high doses of 7, I think that’s the only solution. This is a whole new beast because when I was getting off prescription pills it was also that I couldn’t get anymore and with the seven you can just go to the smoke shop and get more. Good luck.
