I have reactions to white rice and potatos. Not so much sickness but bloating, gas (sorry) and a 3 lb water weight gain the day after.

Just be aware that you will gain water weight if you over indulge with carbs no matter if you feel sick or not. If you keep your calories lower though, on those days it will only be water weight and will drop when you get back.

Beware though... carbs cause carb cravings and sometimes it is hard to stop so do what the good doc has us do with pre-maintenance.

If you are going to have some higher carb foods ... do it with lots of protein and fat to fill you up and give you some control.

Enjoy!
