Here's ANOTHER one for free so you don't have to worry about calling that 900 number and racking up your parents phone bill!
Are your stimulants giving you dry mouth? No matter how much water you drink your dry mouth still persists? Not to fear. If you're going on a speed run/crack binge, a bag of sugar free lozenges should do the trick to stimulate those salivary glands! And make sure they are sugar free, no point in exacerbating that meth-mouth!
I'm not convinced that acid breaks down amphetamines...
The only mechanism I can imagine for that happening would be a protonation (addition of hydrogen) to the nitrogen, followed by amonia leaving the molecule. I don't buy it, maybe you can explain?
I imagine it could be possible if you had some reactant in your stomach that fit the reaction... but I'd be surprised.. amino groups are really stable..
I guess I'm also a little confused about taking Propylhexedrine since from everything I've read it's just like wannabe meth.
