I lost 4 lbs. this week and this is my 3rd week off Diet Coke. It's been something that I've wanted to be off of for a long time. Instead of my soda fix, I've been drinking tons and tons of water. I also started my first exercise boot camp this morning at 5:30am. I was able to keep up pretty well for the first 40 minutes then a ran out of steam and started to get a little light-headed. I took some breaks and felt better. I'll be doing it 3 days a week all month long!
