"i had an operation plus radiation 3 years ago and have suffered from very annoying constant pain ever since. i was on 1 physeptone (10mg)   5 anamorph (morphine 30mg)   5 serapax every day taken at different times. i was always at the doctor and chemist. now i&#039;m on durogesic (fentanyl) patches 75mg instead of all three drugs, and am now pain free. it is a miracle medicine and (for me) has no side effects like morphine and physeptone,and it saves me a fortune! definitely worth a try for all pain sufferers!"
