I hear you - really I do. I gained back the 40 I lost when Ex left and 10 more! I hate it! But I've learned that you have to do your best to dress your current figure then just do the best you can.
I joined Weight Watchers Online 3 weeks ago. I'm down 5. That's not a lot but its a start and I record everything I eat. It has been harder when Ryan has been sick but I'm still trying.
Fruit and veggies are unlimited on this diet. I have to really watch my intake of bread and butter. Yep - those are 2 of my fav things. I find it easier not to eat cookies, cakes, pie etc but it's the bread and butter I miss.
I only weigh myself once a week. I'm trying to get out to the gym etc. I've just decided to do a big gardening project this summer as well that will involve a lot of digging and moving of sand (I'm building a beach). I think that might be better than the gym. Getting the beach is a big motivator for me.
Anyway - have you ever tried Spark People? Its a free online group that helps you stay on track. You can Google it.
But for this weekend - try the suggestions I made earlier and just have fun!
