Who is Davie Mitchell from Trainspotting and what is their importance?

Davie Mitchell is a non-addict member of the core group in Trainspotting. He only appears intermittently but has two full chapters dedicated to him.

When the reader first meets Davie, he is dating a girl named Gail who has been withholding sex recently. He wakes in her bed in her parents' house after a night of heavy drinking. He has urinated and defecated all over himself in his sleep. As he attempts to slip out of the house with the sheets, he is stopped by Gail's mother, who insists on cleaning them herself. Snatching them from him, she flings his feces all over the house.
