Regarding the cimetidine, 2-3 pills (400-600mg; all OTC cimetidine I've seen in the form of brand or generic Tagamet has been 200mg/pill) is a good does to potentiate buprenorphine - no more than 3 pills should be necessary. You can take it with or a few minutes before taking the buprenorphine. The whole process seems to work by inhibiting certain liver enzyme(s), slowing down the metabolism of bupe. The subjective effects of this at 24hrs post cessation of something as short acting as hydromorphone may very well be a bit of a buzz. That really depends upon his metabolism and liver and all that though. He may feel a bit of the bupe, he may not (but it's much more likely he will with the cimetidine).
I say don't take the cimetidine for more than 1-2 weeks simply because of the potential for some serious side effects taking it long terms daily. But one to two weeks shouldn't be a problem in that regard. You should look into these for yourself. The cimetidine may potentiate other side effects of bupe, such as constipation, etc. Generally speaking, taking cimetidine with buprenorphine is something like putting the focus on bupe's agonist properties.
Given how many of our bodies goes through something like hydromorphine, your friend may not even need to wait 24 hrs. I generally didn't have to wait more than 6hrs, although I don't recommend that at all. 12hrs in he should be good and able to avoid precipitated withdrawal, but you're absolutely right. The longer he can put off taking bupe, the better the bupe will work for him and the more relief he will get from it - that's also a bottom line.
In my case, it is amazing how much a difference cimetidine makes when I take it with bupe. It almost turns the bupe into something like methadone, actually preferable to methadone as it isn't as sedating and I'm much more functional given how good I feel. Only draw back is, unlike methadone, taking high doses of cimetidine every day for significant periods of time can have some embarrassing effects.
I don't think one can really say X amount of bupe + 600mg of cimetidine = Y amount of bupe (without cimetidine). It isn't a linear relationship at all. In my case it turns bupe into a superior drug in terms of subjective effects, the trade off long term again are side effects. He'll probably function better on cimetidine and bupe than just bupe alone short term.
I'd say getting more bupe should be the priority over just relying on cimetidine however, and I think you already had this in mind.
