Last year at this time, I was diagnosed with sudden and unexplainable liver failure and so Christmas was a terrible time. Severe nausea and a strict no-fat/no alcohol/no sugar diet resulted in significant weight loss during a time when we humans usually pack on an extra 10 pounds. I was very sick and desperate to get well so I followed the doctor's orders and eventually I was back to normal.
I think I deserve a break this year and I am not going to be concerned with fat/sugar or alcohol intake for the next week or so. I don't think you should be either. Let's celebrate and have a good time!
