Hi my dad has oesophagous cancer and has been on morphein patches and endocodin tabs for pain releif last 2 month and now GP has stoppedmorphein due to breathing problems and has given him patches to help with breathing plus endocodin. Talking to him tonight he sounded drunk and slurring words (even though he doesn't drink) I really don't understand what is going on as he won't give me permission to speak to his drs. I really can't understand why they have changed patches and he can't say either!!
