Hi! I am doing the Atkin's Diet and I Love it - already lost a few pounds and plan to continue this way of life always I gave up the caffeine habit I am taking Ripped Fuel as per the instuctions on the bottle. I definatly have more energy but it tends to make me a little shaky mid afternoon. Does anyone know if it is safe to take Ripped Fuel on a loew carb plan and are these jitters normal? Thanks in advance
