honestly, she needs to wean from both meds with her dr's supervision. They can put her on tapering doses and tell her what withdrawal symptoms to expect...mainly diarrhea, and flu-like symptoms. I never went through the opiate withdrawals, but my friends on the substance abuse forums swear by gatorade, imodium and ibuprofen for generalized aches and pains...oh, and lots of hot baths
Again, though, it would be best to discuss this with her dr.
Hugs and prayers!
