"i broke my neck after a fall from a bridge in 2000. after many failed surgeries, an ans spinal implant that didn&#039;t work, pain medications were my only option. like many of you, i was prescribed hydrocodone, oxycodone, oxycontin, ms contin, fentanyl, in varying orders and dosages, and then methadone. while all of the previously named medications have their pro&#039;s and con&#039;s, i did experience one side effect with methadone that i haven&#039;t seen listed or heard of anyone experience before. after 2 or 3 days on the medication, i started having very vivid and disturbing nightmares. while i understand this may be a &quot;wonder drug&quot; for many of you, there are some of us out there that disagree."
