I also agree with eejit on this one. The only thing that you could have done was to raise it a lot higher, especially after the limping pre-flop so that you would them possibly fold and you take down the action pre-flop.

You can't put them on 66 or 88 so don't think that you should expect that every time. It happens but a lot of things can be stopped by precaution thought. Sorry that happened :(
