Yeah, cheat weekends can be brutal!! LOL. I'm sure a lot of it will come off with a couple of days back on plan. The rest will come off in a week or so and then before you know it you'll be back on track.
I had about a month or so where I was off the pony and I've finally just gotten back on! HA! I was able to *mostly'* maintain.
Anyhow.. keep at it! I hope you enjoyed your weekend!! In the end, that's all that matters!
