Sorry about tummy troubles on top of everything else.
OK, my turn to play MOM....IF your Nutrisystem is really only 1000 calories a day, I'd like to suggest supplementing some additional fruit/veggies to kick it up to about 1200. 1,000 just always feels a little extreme TO ME, and was something I could not keep up for the long haul. Or maybe just bump it up every other day or so. Some people find that varying the caloric intake helps prevent the metabolism from thinking..."Starving". I remember back from the old Weight Watcher days our leader reminding us to eat in our point range...and not just pick one particular number of points and eat that day after day. As our friend Noel would say....just my thoughts.
