Thanks, all. I think for the time being (after this week), I will go back to Atkins. The main reason I switched to CAD was that I thought it would be something Shawn could do; Atkins was working for me. (Although I sure do like the RMs, and I bet CAD would work for me too. ) The problem with doing CAD is that if there is carby food around, that's what he'll eat. He wasn't doing Atkins before, really, but he was eating a lot lower carb than we used to, just by virtue of not having high-carb stuff in the house. And he feels better when he eats that way (salad and cruciferous veggies notwithstanding).

I do think that I'm going to suggest that he get allergy tests done. Who knows? He may be allergic to something we eat all the time.

Thank you all for all your help. I really appreciate it.
