Honestly Bob - and this applies to all of us, in my opinion, you recognize that not drinking during working hours is not special or an accomplishment. In fact it is normal - Europe notwithstanding, here in the US and contrary to what I used to think, you are not supposed to drink during the day. I think keeping this mind helps. Why? Because it helps us get over the novelty and allows us to stop obsessing with the fact that we aren't drinking. Kind of like not taking pride in the fact that we didn't steal something today - we don't think about stealing because it is just not done.
