Live 1-2 NL, misplayed my hand. help?

[Percula]

Bet the flop. The real question is how much to bet...

If the table is playing loose I like an overbet here. If the table is playing passive 3/4 to full PSB (pot sized bet). If the table is playing tight 1/2 to PSB.

When you flop the nut flush you are looking for a way to get it all in not a way to trap the other players.

BTW, slowplaying is a sure way to minimize your big hands. There is a good saying around 2+2, "fastplaying is the new slowplay". Bet your hands, especially live. Just imagine if you had lead for a overbet and the guy had pushed AI?
