Thanks for responding WY. I'm thinking about starting back up with juicing cucumbers or Celery without carrots, and then start mixing in some carrots. I don't have any other health issues, so I think my system just got tired of the volume of carrot juice it was receiving. I only hope I can at least have some carrots in my future juicing, as I felt really good for 2 months until I started to become nauseous.
