Last time I checked, you could still buy Ephedra sinica on eBay by searching for it under its Chinese name "ma huang".

Ephedrine is pretty good shit honestly. I actually find it a little bit more euphoric and tingly than amphetamine, but it doesn't last as long and gives me a headache. I have heard of a few experiences like yours though, of it lasting a few days for some reason. Maybe some people are poor metabolizers?
