I dipped into my flex points last night for the first time since we've started this plan...
The annoying thing was, I got to the end of my day and said "Hmmm. I'm short a few points? How'd that happen?" So I didn't think much of it, had a glass of milk to finish off the last bit of points and went to bed.
This morning, I added up my points to stick them in my side bar, and found the discrepancy. Towards the end of my lunch, I accidentally added 1 point instead of subtracting them.
On the plus side, I did make an Activity Point yesterday - we're getting back into the habit of walking around the block, but I'd already promised myself that I wouldn't use Activity Points until I was getting at least three in per week.
And this was, incidentally, what I was most afraid of, for the Weight Watcher's plan. I'm terrible with numbers.
