Help with changing width of WordPress Post Column

Hi guys, I'm having difficulty modifying the width of my main post column. I hate having too much unused real estate on the template. It's a 2-column fixed WordPress theme. The site is eazycheezy.net and I'm using the Absynthe Theme.

Any help will be greatly appreciated.

 

Try:

http://www.eazycheezy.net/wp-content/themes/themeforest_absynthe_51471/absynthe/style.css

#content{ display: inline; float: left; width: 635px; margin-left: 0; }

Change width.
