Bupropion is a hell of a good drug, if you don't mind the stimulant effects or the constipation. Great feel good and libido drug, although the stimulant effects actually make it harder to get an erection. But it does make me feel better about it! ;-)
I love ephedrine as well, and have been on it pretty much on a daily basis since 1990 or so. Bad for my blood pressure, but great for get up and go energy, as well as clearing my sinuses and diminishing my allergies.
Honestly I love pretty much any stimulant, from caffeine and ephedrine and yohimbine and bupropion all the way up to Adderall. They are definitely not the healthiest thing for me, but I've been on them for thirty years now and I'm still alive, so as long as you can manage them, they have their place in the arsenal.
