Hello everyone. I started the Atkins Diet back in August and in the first week and a half, I went from 191 to 180...things were going great. One day while at work, I had severe abdominal cramps to the point that I was told by my doctor to go to the Emergency Room. After waiting there for an hour, I began to feel fine and they could not determine the cause of the pain which was no longer there. The only thing I had that day were my daily vitamins (which I had been taking all along and had no problems), my Atkins shake for breakfast, water and a plain Hot dog at lunch. After the hot dog the pain started. After I left the hospital...I have been off of the Atkins plan and I intend to start again tomorrow. I read about Constipation and I wonder if that could have been the cause. Any suggestions on supplements that will help with that, I was drinking about 12 - 8 ounce servings of water per day.
