Pizza and exercises

just ate some Dolly Dimple's pizza..It is good but now I feel sick to my stomace..I used to be able to eat lots and lots of it,,,but now,-gladly I must say; I feel stuffed after just two slices!! Must be because I have started my new and improved life!! I have started to exercise really hard 3 times a week! I am with a group of others whome allso tries to get a better lifestyle. We walk up hard hills and mountains, and down. Often in hard intervals (dont know if that is the right word,,,we push ourselves for 4minutes, then we ease down for 4minutes,,then hard again..and so on....)
I feel good!!!

but right now,,I just feel stuffed!!!!
