My husband has been on 5-6 80mgs of oxys a day for 10 yrs. He started subs one in withdrawl hes already taken 2 but I'm not sure if thats true cause he puts them under his tonuge and it makes him throw up...can he swollow them whole and it still work.?? has anyone done it this way and how often should I give him more until he feels better?? 2 Replies
