Time to quit screwing around

It's been just about 6 months since I got to my goal of 100 pounds lost.  And since then, I have been gaining and then losing the same 5-10 pounds, over and over.  This has GOT to stop.  I still want/need to lose another 20 pounds or so, and it's time I got serious and did this.  Tomorrow is March 1st.  Planning on sticking to my calories every day (no late night munching that's not counted) and besides my regular workouts/runs, doing my 6 week 6 pack DVD every day that I'm off work.  I need to get back on track for good!
