Hi Melissa and Welcome!
I agree with Leens that perhaps you may want to consider a different program if Atkins is making you nervous. (although some people's tests have actually improved while on it) Run don't walk to your nearest library and check out CALP and Protein Power. Also check out the ww/lc board and the Sugar Busters board on this site. Lots of good info there!
Good luck and keep posting so that we can get to know you!
