I'm sorry you're struggling.. it's hard when you go off track to get back on. I got advice on here before that helps me. It's take it one meal at a time. if you stray, the next meal get right back on the program. MRC is great, but very restrictive.
I've really struggled this summer... I'm not sure why, but I just couldn't do the program. I didn't want to cook, and was lazy. I felt like crap eating all that food. After a month totally off program, my body hated it. I was sluggish, tired and just felt blah. I resigned last week and feel much better already. I'm back on track.. Lost 5lbs the first week.
Try just getting back on it. Get rid of the junk. We think we're trustworthy with that kind of food in the house, but we're not.. at least I'm not. I just don't buy it anymore. If you have a bad day, wake up the next morning and start over.. You can do it...
