You my friend have been bitten by the music bug. Very dangerous desease! :D There is no cure and symptoms my include but are not limited too:

Sudden development of G.A.S (guitar acquisition syndrome)
An urge to play your guitar non-stop
Withdrawal symptoms if your away from you guitar for more than 5 hours or less
Going crazy if you can't play with other musicians
A constant urge to be onstage
The chance of ignoring the fire alarm when it goes off...
Your wife yelling across the hall no longer phases you while you play...:D

You may only be relieved of the symptoms by giving into them. Trust me, I got bit by the music YEEAARRSS ago...and now have at least 6 guitars, and recording equipment up the @$$. I also got to play with a forming band. That didn't help the bug at all :D
