"i have small cell lung cancer.  my doctor prescribed fast release morphine yesterday, 30 mg and after 2 1/2 tablets i have stopped. i was on norco 10 mg which took my pain to a completely tolerable level.the morphine has left me terribly nauseated and barely able to eat, i itch horribly and it has sapped my energy terribly. also it does not really reduce my pain. i took only 1/2 tab today and i&#039;ve had enough."
