Changes I've noticed

Even though I have only been eating better and exercising for a week I already notice differences in myself.  First off I make better food choices and its really not that hard.  I do have cravings like a chocolate milkshake which I have been wanting for 2 days now but I refuse to give into that tempation its just not worth it.  Secondly I've noticed that exercising is becoming easier.  Now I still dread it but I make myself do it.  Another change I have noticed is its taking less food to make me feel full, I guess maybe my stomach has shrunk alitte.  Also I carry myself different which is a good thing because I have already had one back surgery so I need to get this extra weight off.  It just feels so good to be accomplishing something even if it is in small steps.  My next weigh in is Tuesday and I'm trying not to have a set number in my head so I'm not disappointed but I feel like I've done pretty good so far this last week and I should lose something.  It sure does take longer to lose it then it does to put it on.  I just try to focus on one day at a time I'll eventually get where I need to be.
