i just got myself 80 15mg zydus morph ER's. I gotta say, i think zydus is my fav. brand. with boil drop, I wo'nt normally do more than two pills at a time, and with the M boxes, two is sort of pushing it, its a little much powder and dont work well. but these zydus pills, i was able to throw 4 15mg's into a spoon (boil drop method) and it worked perfectly. and the residue left over wasn't that nasty semi-gellatinous, semi-solid nasty shit (for some reason, it makes me feel better when whats left in the spoon doesn't look like its something very unhealthy)
honestly, the ms-contin, when prepped right, are pretty much exactly the same as the IR or other types of morphine. back when Avinza still existed (capsule w/ beads, no anti abuse) they felt significantally stronger, but that could be because they were some of the first morphine i did. Kadian/IR's/mscontin, nothing compares to avinza.
i personally love morphine. if H isn't an option, morphine is next on my list (ive never been able to get opana's, which im sure are better) diluadid may have better rush, but i have to do like 5 pills a day to stay just barely not sick, can goto bed at 4am and im wide awake by 9am cause im too dopesick to sleep. morphines rush isnt quite as euphoric, but it lasts sooo much longer. other then when my tolerance gets out of control, i dont wake up sick anymore, like i do, but only a little, totally managable and ive got time to prep a shot and find a vein (which for me ranges from 10 seconds to an hour) before i start puking
