Does Withdrawal From Methadone Cause Loose Motions?

Hello, I am a 28 year old woman who recently stopped taking methadone. I quit cold turkey at 15mgs. My doctor gave me Norco 10/325 for the withdraw pain as well as back pain. I have fracture in my spine, which is why I was placed on methane in the first place, however, it wasn't providing adequate pain relief and I gained so much weight on the methane, it made my back pain worse. I never take more than 4 grams of acetominaphen in 24 hrs which adds up to twelve pills of Norco a day, but I have noticed that I am beginning each day with loose bowl movements. Only once or twice per day, and they are normal colored with no mucous or blood, just loose. I do stay hydrated and also take a supplement for healthy liver function since I will probably be on this pain medication long term again. Previous to the two years on methane I was on violin daily for three years. Is the loose stool a sign of the methane withdrawl? ( its been four weeks since last dose) if not, what could be causing it?
My height is 5 feet 4 inches and my weight has dropped from 220 lbs to 190 lbs since stopping the methadone.
Thank you for your time.
