How do you guys play if you are min raised with an overpair in a big pot?

I am continually seeing sets and I'm not sure how to avoid them.

If I fold to a min raise I start getting paranoid that they catch on and do it everytime. Maybe I should fold to them anyway but I am CONTINUALLY getting min raised.

Another problem that comes up is if I reraise I usually have so much committed that I have to call the 2nd reraise all in.

Please help!
