Whenever I eat a carbohydrate-rich meal for dinner, I always have a ‘hangover’ of sorts the next morning. I feel really sleepy in the morning regardless of how much sleep I had the night before. I can’t focus at all and generally just feel like crap. I remember once, about a month ago, I had a lot of peanut butter just before going to bed. Peanut butter has a lot of sugar in it. The next morning, I felt as if I were going to die. There was absolutely no way I could concentrate. My eyes were burning, my legs were feeling weak, I was depressed, and just wanted to lie down and sleep for a couple of months. Thinking that perhaps the sugar had something to do with this, I decided to stay away from excessive carbs in the evenings. I even cut down on the amount of bread I ate. The next morning, I woke up fresh, alert and energetic. I was bursting with energy. I thought I was on to something, so I followed the same principle the following night, staying totally away from simple sugars after , and having little carbs in my dinner. I woke up fresh and alert the next morning! I had definitely made a discovery. I’ve tried the Atkin’s diet and it gave me increased energy levels too and now I understand why.
