Finding the C for overdrinking,

When doing an unintentional model on over-drinking, what sort of things do we put in the C line?

C: 1) I drink too much.
2) want to cut down on drinking. I drink a bottle of wine a night. etc, etc,

I know it’s just one C, and 1 & 2 are specific enough.

Any advice would be appreciated and let me know resources where models are given.
