I need help overcoming my aversion to Lawful alignments.

Hello! In an upcoming PnP game I'm going to be playing a LN Doomguide of Kelemvor. My only issue is I normally hate being a lawful alignment due to feelings of being tied down and restricted. How do I get over this feeling?

Edit: Derp, not PnP. I mean Multiplayer BG game. >_>
