I spent my entire drinking life trying to control and enjoy my drinking-simultaneously. I assumed everyone felt the way I did when I drank...that part of drinking was always wanting more, to the point of oblivion, and that everyone had to exert willpower to stop once they started. I believed, based on how I felt when I drank, that everyone drank to get drunk and that not getting drunk required a force of will.
In my mind, going to happy hour after work to have one beer, or having a drink at brunch and then not drinking more the rest of the day was uncomfortable to everyone and was the price you had to pay. I saw others as "resisting the craving" better than I, and that I just didn't have the willpower or the magic, mental trick to stop the urge.
I had no idea that ~90% had no such urge or craving and that the drink was just that...a drink that they could take or leave. To me, it was the axis on which my world spun....mentally and physically.
It was such a huge relief for me to come to understand that allergy aspect, and to realize that I was comparing myself to people who had an entirely different experience when they drank.
