"i have a chronic illness called ic or painful bladder syndrome, which keeps me in really bad pain 24 hours a day. thank god i found a great doctor who prescribes me the fentanyl patch. this has given me my life back to me.  i can pretend i am not sick most of the time thanks to this great medication.  i take 75 mcg every 3 days.  wish it was was every 2 days though, the 3rd day is really rough and the pain comes through on the 3rd day."
