I've had those feelings.. There are just days that I can't do the program. I know it's me and not the program. I just try to get right back on the program. I've never tried medi-quick, but I hear on here a lot of people who do. I love food to much to give up the little food that we do get to eat.
My problem is that I get in a rut. I tend to eat the same things over and over and that gets boring. I notice that I can stick to the program better if I change things up.
This diet is like any other diet. If you don't do maintenance/stabilization, and stick with it, you will gain the weight back. We are all here because of how we used to eat. If we got fat the first time, when you go back to eating that way, you're going to get fat again. I look at it as a lifestyle change. Through the process I'm learning how to eat off program for an occasion then get right back on it.
You can do it... Just take a deep breath..
