Yes, just 4 days. Is it really normal to feel this bad? On day 2, I had terrible cravings for bread, I have never felt that way! But what is funny is on day 3, I had no appetite at all! I had to force my self to eat anything. I was so dizzy, and tired today I had to go off the diet. I eat a sweet roll, and about 10 mins later I was feeling better! I can't say this is because I eat a lot of carbs, I have been on an off again a low fat diet for 5 years. But still a majority of my cals, were some type of carb! I do plan on giving it another try. This time trying more cals, I have a hard time with adding cals, and fat... wish me luck...
