Weekends are my nemesis

I don't know how I'm ever going to lose weight when every week includes weekends. That's when all of my naughty urges come out! Monday through Wednesday, I'm by the book perfect! But Thursday night I start to veer off into my own little world. I find ways to substantiate every little "cheat" --- ohhh I didn't have a full serving of X so I really have 2 points left... or well, I did lift extra high on the leg lifts in Zumba tonight. ARGH! I'm telling you, Thursday morning, the scale is always at its best... then come Monday, it's a hot mess. I can't live without enjoying myself, so that's not the answer... but there has to be a way to have my cake and eat it, too (and not have it show up on the scale!) Cheers, S.
