I have decided to try out these weight loss aids and bought a pack of Stack II a few days ago. I have also read reports as I was worried about using ephedrine.
For three days I have used these and have found them terrific for increased energy and gym workouts have been much easier. However I have noticed my heart beating much faster, one of the documented side effects.
I am wondering if this means I should stop using altogether. Do most people who use the pills experience this symptom?
