Sick as a Dog - Aerosmith. Am I close?

[aarono]

I found the chord sheet for Sick as a Dog by Aerosmith and tried to play it by ear and following the chord changes. I'm new at trying to play by ear but I think I can play something close to that would fit.

I couldn't find any tabs on it so perhaps this is a good exercise in developing me as a player.

Has anyone played this song on bass and can tell me if it just simply plays roots of the chords? If I do that and just follow the rhythem and chord changes I can get it close.
