Lindsay, I'm sorry that you had a stomach virus (blech!) and that you are finding yourself a bit more weak and tired than before. Don't worry, though...and treat yourself kindly for the time being. We all go through a phase where we feel someone zapped our energy stores; that's because we've undergone major, major surgery! I'm just now 5 weeks out from surgery and still have days where I feel I'm trudging through mud. I believe those ahead of us on this journey who say, "It'll get better and better." In the meantime, your fantastic weight loss is some small consolation, no?
