Had a breast augmentation on Wed (Jan 7).
Was prescribed hydrocodne/acetaminophen 7.5/325mg, Valium 5mg, and Promethazine 25mg. 
I did not realize until tonight (January 11th) having drinks with a friend that the half life of Valium is so long.

Don't do it again: This won't hurt or kill you, but you do need to show this helpful drug the respect it deserves. It's important to space the doses out so that you don't get sick. Up to 4000 mg/day is fine but you don't want to take even this much all at once -- you might overload the enzyme that processes it by the normal pathway. ...Read more

What amount acetaminophen in a day?

What amount acetaminophen in a day?

Least amount...: ...necessary not to exceed 3000mg in a 24-hour period of time. Don't take it all at once either, because it won't be any more effective in mega-doses. Not the best pain med available over the counter, just useful for fevers. ...Read more
