instead of going to work and drinking before getting in there I could... stop for coffee
instead of going to work and drinking while I'm there I could.. grab a lollipop
instead of going to work and self-harming I could... scratch the 'itch'
instead of calling in sick I could... make an activity prediction chart (PM me)
instead of binging on food I could... make a behavioural chain analysis (PM me)

You could decide on a reward (not food). List your positive expectations of a reasonable goal and reward yourself for accomplishing them.
