I have never used stimulants but I have heard good things about stuff like aderal and other meth type stuff. But fuck that, not for me.
Our "road aspirins" were mostly just dexedrine, preludin, ionamin, etc., commonly prescribed diet pills in their day.
The meth was only for special occasions like stadium shows.
You have to remember though that meth wasn't the same in those days. It was synthesized from phenyl-2-propanone, a darkroom chemical that produced both dextro-rotatory and levo-rotatory methamphetamine. Now it's made from pseudoephedrine, which is sold in the dextro-rotatory form and produces dextro-methamphetamine.
I may joke about kids nowadays not being able to handle their crystal meth, but I do realize today's meth is twice as strong as what we did back then.
You're wise to take a pass.
