Squidgy,
Be very very careful with Ephedrine. I know it is natural, but it is NOT good for you. If you asked your doctor, they too would agree. The reason you are receiving more energy from it is that it speeds up your heart rate. This is all it is doing. Your heart beats unnaturally fast, therefore giving you more energy and a higher metabolism. I think you should maybe consult your doctor more regarding this, as I am not one. But IMHO it is NOT good for you whatsoever.
