Although I suspect that some of the ADD medications are, perhaps, inadvertently playing up some of the adverse effects. Cadaverine is after all derived from lysine which dexedrine is salted with in the medication Vyvanse. I've never taken it before so I don't know what the deal is there.

Benzalkonium chloride has those methyl groups. Something like methamphetamine. Which not a very good ADD medication at all.

Part of what makes dexedrine effective may be the lack of the -OH group. The protein of the receptor is -OH phobic. So it would not have nearly the effect on someone who does not have ADD. Their protein is -OH philic.

It took me 17 years to learn the hard way.
