Diet Update – Day 116 of Atkins Diet Today was the first day I had sugar in 116 days; made me feel sick. I went to a seafood buffet and had a great meal, but did indulge in desert for the first time. Since it was a buffet, I had a bite of several desserts. My reaction was immediate: First I got a sugar high, then I felt lightheaded and had a hard time walking from the restaurant to my car, by the time I got home I had a headache and started drinking water to flush my system. It was a really bad reaction and made me have no desire to do that to my body again. I really paid for breaking my diet rules, I felt awful.
