I've never been successful at withdrawal attempts which is why I've been on methadone for 15 years. I do have severe chronic pain that is cancer related. I am being very under treated for my pain and it is upsetting. I suffer every day: ice packs, heat pads, epsom baths, meds like Advil 600 mg and Tylenol 1000 mg together for relief that never comes. I take Gabapentin up to 800 mg at bedtime. I have many prn meds but this page is only asking for 3.
