To update, I spent the morning with my doctor and at the lab having many vials of blood taken and an ECG because my blood pressure was very high (it has NEVER been high before) and I have to get "samples" for the lab as well to check why my stomach is so upset. She did read the labels on everything I am taking - supplements etc., plus she examined the ingredients in the Advantage bars and said they should not be causing what I am experiencing, except perhaps the Vit. C! She said to cut it back to 1000 a day and I have to go see her again on Friday morning. I'm hoping my blood pressure was high just because I had just done my 30 minute cardio workout followed by 10 minutes in the steam room...anyway thanks for your concern, I wanted to update you.

Forgot - I'm also going for a lactose tolerance test on Friday.
