i think this song is about how he was at a bar and got drunk (got caught runnin up a tab) and he was too drunk to drive home so he had to take a cab. (couldn't drive home so i had to take a cab) he meets the girl who hes sharing the cab with and even though they start having a fling, he did something stupid to her because he was too drunk. (but the alcohol made its way down;she was the last thing that i saw last night before i hit the ground) so basically he liked her but missed his chance because it was the alcohol talking
