YES, YES, YES - you (we!) can do this! I will be on Day 6 tomorrow. Yesterday was an awful, awful day. I was irritable and tired because of the carb/sugar withdrawals and PMS'ing on top of it. So what did I do? Yup, I went to sleep. I was hungry but there was nothing I wanted to eat. So, yeah, I understand what you are saying. Honestly, it was just my way of pouting. LOL
My fingers are crossed for you that those 15 pounds are lost by Halloween!
