When is it enough?

Is it when you’ve finished your glass?
Is it when you’ve finished the bottle?
Is it when you’ve fallen down?
Is it when you’ve blacked out?
Is it when you’ve made yourself sick?

Or is it when you’ve worn your body down to the point of no return, leaving your family with no other option than to watch as you slowly drift away?

So tell me, when does it all become enough?
