Thanks much for the help. I'll go back and review the Protein Plan literature regarding nutritional supplements. I'm not very good (i.e. compliant) when it comes to taking things in pill form. But perhaps this lifestyle will inspire me to be more actively engaged in taking good care of myself - including taking vitamins. For now, the potassium is non-negotiable. I went hiking today and the only thing that made it possible was taking potassium with meals. It virtually has eliminated the feeling of heavy, crampy legs and shortness of breath that I was getting before.

Cheers,
