Aspartame

I have been following Nutrisystem for a while and have discovered a few things about myself.  Aspartame may be an alternative for sugar, but it has a downside.  I can guarantee that one hour after consuming a food containing aspartame I will be hungry again.  Not regular hungry, but starving hungry...feed me right now hungry.  Therefore, I am trying to enjoy my food without any sweetener.  It's tough.  Some days I would rather be fat.
