My doctor told me:
Take lots of hot baths or motrin for the aches (no more tylenol if its the pain pills you are coming off of because you dont want to cause more damage to your organs)

Sleeping pills (Precription if you have them, Valerian Root is also good, or try Unisom)

Centrum or Prenatal Vitamins

Extra Potassium will also help your muscle aches.

Immodium or Lomotil for diahrrea (thats the only thing immodium is good for)

If you develope a cough its because the Hydrocodone is a cough suppressant (sometimes I would cough so bad I would vomit)

Phenergan (promethazine) helps too, but it knocks me out. Its for nausea

Lots of fluids. Lots of sleep The worst of it is over within a week depending...
