Basically, there are four options that are all fine here:

1) Fold.
2) Raise and fold to push.
3) Limp and push over a reasonably sized raise. If he checks and you whiff, bet.
4) Limp and fold to a raise. If he checks and you whiff, bet.

I'm sure one is better than the other in this specific instance, but it really depends on how he views you and how maniacal he is. It's also very important to vary what you do here if he's even the slightest bit aware of what's going on.

I usually complete the first time, and if they raise, I'll fold with the intention of complete/pushing the next time. I mainly do this to learn how he'll respond to a limp and to set up some nice metagame where both my limps and my raises look stronger to him. But, this can change pretty easily depending on very specific reads.
