Is ephedrine supposed to supress appetite, speed up metabolism, or both? Because when I take it, it makes me really hungry. I am just wondering, for example: Lets say I normally eat a daily diet of food that pretty much maintains my current weight and body composition. If I continue to eat the same and exercise, and add ephedrine, should I lose fat without chanign my diet, assuming I was eating as diet that is exactly and maintenance levels. I always assumed ephedrine would speed you up, but I also thought one of the effects was dual in that it would speed you up and eat less. Whenever I take it, I cant stop eating. So I am going to try to just eat what I normally do.
