So interesting.

Is it an addiction?
Is it not?

I know that, in the grip of it, quitting is the damndest of difficult things to do. And I've seen, again in my own experience, that it is possible to go years without thinking of it.

Yet again, I've seen it come back... just as fiercely and quickly as it all started. All it takes is one slip...

So yes. I actually do think it is an addiction...
among other things.
