mixing them both together at steady doses is like doing cocaine and drinking alcohol (you drink like a fish, cant get any drunker, just keep drinking), the xanax will allow u to feel comfy enuf to do more ritalin when ur not really achieving any euphoric effects significant enough from the ritalin. its good to take a hefty dose of xanax when the ritalin wears off as the crash is horrible. D-amphetamines (dextrostat, dexedrine) is the way to go for uppers. dexedrine hands down, its pure d-amp, less binders as its beads, if u can crush it up into fine powder your pretty close to its pure form, smoother effects, less of a crash, more euphoric....adderall is a mix of 4 amphetamine salts (including d-amphetamine).
