The difficulty of stopping at this stage is that you try and convince yourself that you're not quite there yet.
Not just at this stage - I was drinking all day everyday, punctuated by 'time off' and the sicknesses you describe...and I still wasn't an alcoholic to my mind.
Alcoholism is incredibly powerful in its delusion - it takes strengths like our intelligence and determination and uses them against our well being..and we barely notice.
You're streets ahead of where I was in self awareness, El C. It's a good thing to be. I hope you follow through and ultimately act on it
