The only one that worked realy good was Ephedrine but its forbidden in most countrys now and hard to get. You can drink the Chinese Ma Hoang tee if you want.
This stuff is a little more akin to a prescription amphetamine than to over-the-counter ephedrine. And you still can buy ephedrine over-the-counter as an asthma remedy. It's known as Bronkaid or Primatine tablets. I'd recommend the Bronkaid with it's higher ephedrine amount.
But yes, ephedrine is effective, but only mildly so compared to the prescription stimulants.
