we're addicts. We're obsessional. That's why we're here on this forum.
IMO, whatever our drug of choice was, it was just the manifestation of an underlying condition.
But we can learn to control ourselves, we can learn to moderate our behaviours if we think they're out of hand.
We can also try and focus ourselves on positive outlets like SR.
As long as you are helping people while you're here, and as long as you're not avoiding responsibilities by being here, or isolating - helping people and learning more about addiction and recovery is no bad thing to be fixated on....
and, regarding your sig - I do think you think too much
