I have had problems with constipation for as long as I can remember and I often go weeks without a bowel movement but since I have started taking Methadone my problem has become much more severe. Can you please tell me what the risk factor is for taking Methadone and using the Fleet-enema? My only other option at this point would be having a Dr. scoop out the impaction. ( sorry if that was to graphic but I can't think of a word besides scoop at this moment. ) Please help me with this as I am really running out of options fast. It has been 2 weeks since my last bowel movement. Thank you for your time and consideration in reading my mortifying but serious question.
