Hello i currently have a high tolerance for pain killers and my choice of painkiller is hydrocodone, (50mg) since sometimes my choice of painkiller isnt around sometimes morphine pops up but of course each painkiller has its own type of high. Right now i took 120mg (3 60mg Morphine) but what i dont like is i just tend to feel it only on my legs. Id wish to direct this to my body instead. But i get more of an intense feeling in my legs every time i take morphine which is why i preffer hydrocodone because its directed towards more to my stomach. Is there a reason why i feel it more to my legs rather than my stomach? And also is there a way to direct to my upper body? And what would be a good opioid potienater for morphine? (Xanax?)
