I have a sever case of Interstitial Cysitis with Hunners ulcers and have been seeing various pain specialists the last 10 years, I was just recently diagnosed with central sleep apnea and had the overnight study and had nearly 40 episodes of breathing problems, so the pulmonoligist told me that she was very very scared for me , she said all it would take is one extra pill in a moment of forgetfulness and thats it I will be dead, so anyway I was on Methadone and recently switched to MS contin as the pain Dr. thought this would help the sleep apnea, but she is not convinced, so I take 4 MS contin ever 6 hours and yesterday I cut back to 3, I really dont want to go cold turkey as I dont think I could hack that!! Thanx for any help!!
