Using pseudo as a stimulant? Please. I think for your probable purposes, you really don't want to be starting out with pseudo that needs to be seperated from an NSAID.
If by any chance you're serious, then frankly, you're better off with iced coffee, energy drinks, stackers or whatever other stims you can find at your local 7-11. Pseudo's pretty much useless as a stimulant, functional or otherwise. And if you're doing the other thing...sigh. If you don't set yourself on fire or get a lungful of toxic fumes/DEA agents kicking the door in, then good luck...I guess, but keep it to yourself. More bathtub crank cooked up from impure ingredients the world doesn't need. If you're looking for tips on a site like this for the extraction, I'd gently suggest you may not be qualified to undertake such a dangerous and delicate operation.
I did, once, at the tender age of 19, try using both pseudo and ephedrine proper as stimulants - I'd done a lot of speed in the preceding months (sulphate), and couldn't feel them at all, beyond a vague nausea from the sudafed. Which ruined a wonderful meatball sub, because the shit wasn't even strong enough to suppress my appetite for a couple of hours.
So either way, don't do it. If you're looking for a functional stim, caffeine at sensible doses and regular intervals is your best bet, assuming Ritalin/Modafinil are out of reach - if you're looking to cook meth, you're unlikely to succeed, and if you do, the end product's going to be full of nasty impurities.
