Do you take your vitamins before or after lunch?

I'm on a caveman diet, or paleo diet if you prefer, but I don't always stick to it, so I take a good multivitamin to fill in for the nutrients I'm taking. I also take some omega 3 capsules (have to make sure I'm getting enough orac value!). I keep switching the time when I take the vitamins. I used to take them at breakfast, but now I take them after my lunch.

The only problem is, occasionally I get fish burp when I take them after lunch. But I never have the fluid on hand before lunch (has to do with where I work, no easy access to cups and a drinking fountain) to take my vitamins beforehand. I thought about bringing my own bottle of water to work each morning , but that's a hastle and could also be expensive.

So, I'll stick to taking my vitamins after lunch. The only other option is before dinner, but I don't bring my vitamins home with, so I never have any on hand to take! What do you think of that!

Oh, by the way, I always buy my vitamins online.
