I felt really bad the first day: nausea, headaches. I almost ralphed in my office. Very bad. Then I just got myself an Odwalla and drank a little bit. My headache and nausea went away. Now I was going through caffiene and carb withdrawl. And I think it was all to much for me. So the first day I wasn't able to stick to under 20g a day (ate 70g), but the second day I made it to 30g. And next day made it to under 20g. I don't know why Atkins is so strict saying that you MUST stick to below 20g a day. I think it would be easier just to have a few sips of juice when feeling really sick. Maybe it inhibits future weight loss, but I can't see how. I'm on day 4 now and have lost 4 lbs.

I figure withdrawl is withdrawl, you can do it slowly or go cold-turkey.
