One comment would be: Can you give up the coffee? Atkins is very clear about needing to cut caffeine. The other thing Atkins is clear about avoiding is Aspartame - that stuff in Equal.

If you're already in pretty good shape, that's probably why you're not seeing the first week loss. In my humble opinion that first week loss is all water. Don't get me wrong, I'm losing inches and happy about it. I really couldn't care what I weigh so I rely on the measuring tape to track progress.
