Thanks all. Lobo: He is taking 8 mg's too. He just started yesterday, and he hasn't complained about being nauseous, but he definitely has lost his appetite. He usually gets home from work and immediately wants to know what's for dinner. I haven't heard a peep so far.
I was so baffled that he went back to using after a good 4 months clean, but he said the craving takes at least a year to go away. I guess he'll be taking the suboxone for awhile. But whatever works.
