I was in the hospital and on IV Morphine every four hours for three days, discharged from the hospital and given a script of 21 Oxy 10-325. The Oxy was gone in about a week followed by one day of 52.5 mg of Hydrocodone with little effects. How long should it take for my tolerance to be back to baseline? My opiate use has been limited to the last 21 days or so.
