I am on day 15 and yesterday I had similar reaction. After taking my multivitamin (which I previously had no issues with) I started to feel sick. All day! I dry heaved last night. Can't stand smells, I feel a little better today - haven't taken the multi vitamin yet. I had some water, 2 oz of protein shake and went and got a sugar free slurpee. Gonna go back to bed for a while and see how I feel.
