Hi I just linked to you from the water challenge. I noticed you are on the blue team too. I'm on the ww core plan. Which one are you doing? I was having that trouble last year when I was working a clerical job, getting tired at my desk. I started keeping a jar of peanuts at my desk. I would just take a small handful to keep me from getting tired. They have a little bit of carbs and a lot of protein. I think the protein helps. I have type 2 diabetes and I always have to have a protein with my meals and snacks to slow down the carbs getting into my system too fast. You needs carbs too for energy and protein helps you feel full longer and not so hungry. I was having trouble my first week of the core plan just feeling like I was starving and they told me I wasn't eating enough protein. LOL of course maybe you just need more sleep. I hate that when I'm going on a trip and havent had enough sleep. :) Have a great week, and hope your trip went well. DD
