If I don't do enough of an amphetamine then it'll make me tired as fuck, but with a high heart rate. Also if I don't have any food (and low or no magnesium) in me then I won't get as much energy.
Supplementing magnesium(helps make food into energy, and amphetamine/alcohal/cocaine/coffee all empty a lot of it) and eating beforehand will help in the future. Just watch yourself and don't over use..
I'm willing to say its cut too or you have been binging too long and shot your tolerence up
When I use daily for too long I stop getting rushed. I have never done a shot (or lines in the day) and got sleepy but I know people who have. Those people have been using far tp long.
Yea that really doesn't make sense. Paradoxical reactions do occur but it's more likely you just snorted a big line of (insert white powdery substance)
