Matt and I are giving up sugar for Lent. That's 40 days from yesterday til Easter of no treats. I did this last year in May and it was a good (although challenging) experience, and so I decided to do it again. We're not Catholic, but decided it was a good idea. Matt has declared that he gets 2 exceptions to this rule. 1) Costco cake for his birthday, and 2) Donuts on moving day. I have declared that I get 2 exceptions as well: 1) I can put a little bit of sugar or some type of sweetener in my oatmeal and 2) If we somehow win a vacation in the next 40 days, the deal is off.
We have also started doing Jillian Michael's Ripped in 30. It's only Day 2 and I'm dying.
