You are trading a very minor opiate problem for a hard core serious opiate problem if you do not jump off sub immediately (5) to (7) days.
Yes, it is completely crazy to take for a 20 to 30 mg Vicodin habit.
I have weaned off 180 mgs of Rixys, Fentanyl patches, dilaudid and much higher Vicodin habits.
Jumping off of subs after a couple of weeks of use can be a nightmare and second only to coming off methadone.
Subs are also a very nasty synthetic drug that wreaks havoc in your system. The body cannot reach homeostasis with Bupe. Natural opiates are actually very, very harmless to the body. The dependency and Tylenol is what is the killer.
