When you started the new 2 week cycle did you start back at the same dose as you started with on the previous cycle? Well, I guess even before that, are you doing the same dose over the 2 weeks or increasing it as you go (like one does w/ clen)? Are you feeling sick or just the same type of shakes from too much coffee? If you are feeling sick, stop the ephedra. If you are just getting the shakes, you might just drop the dose back some.
I built my own stack w/ E, C & A and I didn't like it at all. I've also taken ephedra by itself and had a lot of trouble with it. I'm still completely satisfied with OTC stuff like Thermorexin for the little additional that you get from clen & / or ephedra. But basically if you don't feel good, stop taking it to make sure that the ephedra was the problem and not something else. Then try again if you so wish, but maybe at a lower dose.
