So...I lost three lbs last week. YAY! This week has been rough. I can't seem to get any energy and my throat is starting to hurt today. I am hoping that it is just thirst because I haven't had a lot of water lately, but I'm afraid I'm going to get sick again. I don't even have any sick days at work anymore because I've already suffered through two colds since November. The last thing I need is to get sick again. My doctor said I have a weak immune system...but goodness sakes! To the vitamins!
