How do I take a multivitamin that makes me throw up because it's so gross?

I have these B-12 multivitamins and the past two times I took it, I threw up. It kind of has an acid taste, like citrus. The first time, there was no food in my stomach and I retched into the kitchen sink. I saw that the bottle suggests taking it with food. Today I tried by eating some peach about an hour before, and then had a marshmallow right before. I took the pill and then ate about 10 Cheese-Its. About 5 minutes later I threw up.

How can I take a multi-vitamin and keep it down?
