I am on my 7th day and have lost 11 lbs. I am feeling nauseated and now I have chills and am so lethargic. Is this right? Everyone else at work on this has so much energy and feel great, am I doing something wrong. I am trying to do 20 carbs a day sometimes I might be a little less. Today for instance, bacon and eggs for breakfast, roast beef, havarti cheese, cucumbers and celery and no sugar jello for lunch. Any ideas, I am a little concerned!
