Grouchy, but losing weight

I've been working out with a personal trainer at work, and let me tell you that her first 5 minutes are harder than my 30 minute work outs, and I love it. I love the fact that I am working on being healthier and losing weight that I can no longer claim as "baby weight". She even has watched my heart rate while exercising and after to see how healthy my "heart" is and I've seen improvements there too.  When you have a schedule and all you have to do is walk away from your desk and show up- it helps. It makes me more aware of what I am eating too because I know how hard it is to work that extra helping of whatever off.  On the other hand, being sore, and more tired physically, and eating less has made me grouchy.  I think it's understandable though. Think of people to quit smoking... and how grouchy they are. It is the same thing in trying to lose weight and not using food as a stress relief.... but inside I'm very happy I'm getting it done:)
