i know what you mean angie hun, i was on zomorph, which is just another version of mst, and i also take oramorph too, and it does give good pain relief, but if you miss a dose, ouchhhhhhh, been there, so i know how u feel, i could always tell you when i was an hour away from my next dose, as the pain would start to increase. but i also found that since my op in april, i wassnt getting as good a pain relief, ithink it was cos of malabsorbtion, or could be im more active now ive lost weight, im not sure. so im now on pain patches, which are good, but i still need oramorph.
good luck with the new regime huni, i really hope it works for you, and gives you some really good relief, maybe at last you can start to have some quality of life again.
great big hugs n snuggles xxxxxx
