Altho vitamins are really important, for most U dont need to take 100's to be effective. You do need to be on a really good multivitamin, calcium-magnesium, and most people find that potassium is really important...at least the 1st few weeks because low-carbing tends to deplete your system of this. I have rarely heard of anyones tests sky rocketing, if they do it is because they are "fat" sensitive. Im sure U will be just fine. Wait for about 2 months then have it re-checked. Saccarine really isnt very good. Can U switch to a different brand? Also try to keep the artificial sweetners to a minimum. I wish U lots of luck!
