Nerves are kicking in..

So I have a surgery date of August 3, 2011. Today I got the call for the date of my pre op testing... yeah... now is when the nerves kick in... 

I know that this surgery will make me feel better, my back in general. If you have ever been pregnant then you know what a strain that it takes on your back no I'm not pregnant lol... I just have 25+lb of excess skin hanging off my waist. I'm also not looking forward to the weeks of pain... I am pretty much always in pain but... I don't know how different this will be...
