It looks like you have a very strong desire to quit, but also you are having a battle with the obsession. Alcohol is never far from your thoughts... pleased with your flight because you didn't take a drink etc. Still a lot of thinking about drinking.
My alcoholic mind could take that little slip and say, well, the world didn't end, I didn't develop any craving like they said I would, maybe I can handle a little bit more.
But, as it happens, I no longer suffer from that obsession. When I take a flight, which happens quite a lot these days, I am always glad when it is over, I am grateful for the people I meet, the airline food etc, but drinking or not drinking does not occupy my thoughts.
The trouble with the obsession is that it has the power to trump memory. The memory of the last disaster was never enough to keep me sober. The obsession had to go if I was to have any chance.
