The entire "hot rail" thing is more trouble then it's worth IMO - either somke from a bulb, snort, or EAT - yes, EATING METH is a WONDERFULL THING!
People assume it's a waste - but it can be GOOD depending on WHAT you're seeking... if you want a hard rush, then you gotta smoke or bang.. a decent rush requires you to snort it at least, but if you want PURE energy for a LONG TIME, then EAT IT!
Take a good sized "line", put it in some coffee, and drink - this will keep you wired for FAR longer then any other means.. perfect for those Mondays or if you need to get your house cleaned!
