Meth, or anything like it, isn't my idea of a good time. I can't stand (most) stimulants. I don't mine coke, or a few of the really selective DARIs, but otherwise I hate anything even remotely stimulating.
My cup of tea, so to speak, is opioids, psychedelics, and dissociatives, methoxetamine and 3-methoxy-PCP in particular. I find IV MXE takes care of the neuropathic pain in my leg. After I had surgery, they fucked up and left me with neuropathy. Its not going to heal, and regular opiate painkillers are not, in general, very effective on pain thats a result of nerve damage. NMDA antagonists on the other hand are brilliant for that.
