Terrible week, looking forward to making this one good

It's been about a week since my last blog.  I pretty much checked out this week and am expecting another gain on the scale tomorrow.  My ankle still hurts so I haven't exercised, but in addition to not working out, I have also eaten poorly.  I also drank tons of diet coke.  It was a pretty stressful week at work which consisted of late nights.  A late school night for me is about 11:00, considering I love to go to bed by 9:00. I used the excuse that I needed to stay up later as an excuse to drink caffeine, not good.  I am determined to make this week be a good one.  I will get back to eating better, drinking water, and working out.  I don't think I can full out run or jog still, but I will at least do some sort of physical activity.  How many times am I going to fall off and get back on this wagon??  I have no clue, but at least I still want to get on and haven't given up.
