Hello, My name is Christine I was sleeved on May 9th, 2016 so I am more post surgery than some and must say I get tired too! I sleep 9 hours a day during the workweek and often take a nap on my days off. I feel more energetic if I remember to eat more often. This is hard but it also helped with a 3 week weight loss stall. I am down 34 pounds started at 206 and am down to 172 ish. This is the lowest I have been in a while. As long as I remember to drink a Protein shake, take Vitamins, and stay busy and EAT and Drink I lose and feel pretty good but it doesn't take long if I forget any of these things to not feel good.
