hi tiniateresa, I'd say no on the cleanse with the painkillers based off what painkillers do to your body and what the cleanse does, it might not be a good combination. i understand how you feel about wanting to start right away, but give it some time. wait until your strength is up and you're on no meds, or at least less meds. I'd give you the same advice eklutna, Start by cutting out all meat and dairy for a week. Then going raw. Then doing juice for at least 3 days.
additional info on who should not fast:

* People should not try juice fasts before or after surgical procedures.
* Fasting can reduce blood proteins and change the way prescription drugs react in the body.
People taking prescription medications should consult a health professional skilled in detoxification before trying a juice fast, and should never discontinue or reduce their medications on their own. Taken from http://altmedicine.about.com/od/deto...ce_fasting.htm
People with life-threatening conditions should not fast, especially those who are emaciated due to cancer, TB, or AIDS. Both Type I and Type II diabetics should be under supervision if they decide to fast, but it is not recommended. Pregnant women, infants, and those with kidney failure are discouraged from fasting.
