Welcome to the forum! Those were pretty medical questions that ought to be discussed with the doc (as you have done). I can say that it takes awhile to get stabilized on suboxone, certainly more than a few days. Where did xanax come from? From what you said, that sounded like a wild guess, did the guy have some or say he did? As to seroquel, a number of us who have been on suboxone have been prescribed this drug a "safer" alternative to sleep meds, etc., and many have reported all sorts of weird effects. At least the guy has sought help, now its all up to him (relying on just meds won't cut it). I'd say you might want to give him a break and wait until he has a chance to stabilize and see what happens!
