Dopamine

So we're all aware of the effects of dopamine on the brain once we have have some new interest, it goes full blown and we get locked in and it's very difficult to break us from it. We will get to the bottom of whatever problem we're trying to solve etc.

My question is, when you don't have a particular interest in mind, do you guys feel the massive drop in dopamine levels and reach out for chemicals that will spike dopamine levels, or is that just me?
