Thats the wonderful thing about WW, you can splurge like that....and still lose! If you really honestly were craving it, then you did right by getting it...you know now though, that sometimes afterwards you regret it, and it will get you thinking twice next time.
On this program, I cheat...I always will...thats why I love flex. I can be bad and jump back on the wagon and still have a successful week as long as all 7 days aren't cheating days.
You did good, you had your fun and the craving was fulfilled
Now you'll move on, no guilt.
