Should I take my pills with food?

[jenna30]

some medications are supposed to be taken with food and some are not, so I don't know which to do.

Should I take the pills on an empty stomach? How long should I wait to eat again? How long before I can have caffiene after I have taken the pills?

Or

If i should have something in my stomach is there anything to avoid? Like taking it with milk instead of water?

Thanks for any help!
