You can do it - and it sounds like you're doing a great job so far. Your right the weekend is the hardest (for me anyway). I got through last weekend by sitting at the pool with a good book, swimming (a little) and going to the park with my son. I stuck to movie rentals because I didn't want to look at food commercials. I also took a nap each day to rejuvinate. I plan on doing the same this weekend, and have a list of things to do - like help hubby clean the garage, wash the cars -- stuff like that. I've nixed all social activities until Mother's day. I know this is a strict regimine and giving up social events isn't something many can do. However, it's what works for me right now.
Good luck and please check in when you can. I'm rooting for you!
