I choose both. I like to snort it, because it gives you a real good rush, and a more lightheaded upity high. I like to swallow it, because I feel like it gives stronger body buzzes. If you do a couple lines, and throw the rest in a drink and swallow it, this seems to be most effective. I tried it yesterday with 40 MG. I couldn't sleep at all last night though, so I got up and did some situps, I'm going to eat breakfast, shower and digest, than take another 20MG XR so I don't pass out in school today.
