Cover art for Big Empty lyrics by Stone Temple Pilots

Yah I agree with the drug-adiction analysis. I also think though that there's more about conscience in the song. 'Her dizzy head is conscience-laden' He wants to be normal and be with someone but it's difficult and he portrays her as either wanting to screw him or get him high. Song is a big wake-up for me.
