I have never been able to understand people like you. I do not possess the ability to have just one (fill in drug of choice here).
It is called self control. And as I mentioned, I had three relatives that were alcoholics, and I observed them growing up and watched as two of them almost died the same night in the same hospital. Can't tell you how many nights were were awakened when I was a kid by one of my father's two brothers in the middle of the night, who was drunk as a skunk.
After the first time I ever got drunk, I felt miserable the next day. The day after was the first day my parents came down to my university to visit. When we went out to dinner, my mother could tell there was something wrong with me. I told them, I partied the night before and had too much to drink, my mother's response was "eat something, you will feel better".
I spent much of my adult life on the road, living out of hotels, and would dine with folks that ordered a bottle of wine, expensive wine, with dinner every evening. I learned to appreciate fine wine. I am perfectly happy drinking one glass of wine with my meal. Occasionally, this cohort would order a 2nd bottle of wine, and I would end up having a 2nd glass.
I believe red wine in particular is highly beneficial with food from a health perspective. I saw an American doctor, who did research in Europe talking about the huge benefit and reduced likelihood of having heart issue with regular consumption of red wine. He indicated it reduces the stickiness of one's platelets in the body from consuming red wine, reducing dramatically the risk of heart attack. That is my primary reason for consuming alcohol.
Plus, I love green Chartreuse, and I have learned it has incredible medicinal qualities. If I become symptomatic with viral symptoms, ONE drink of Chartreuse before I go to bed, and 4 out of 5 times, I would awaken with no symptoms, feeling normal. I have been drinking it since 1982 when I discovered it at a high end restaurant in Washington, DC.
My favorite whiskey presently is orange flavored Jameson whiskey. Very tasty, and smooth. I am a firm believer that whiskey also enhances one's physical life, prolonging life, but again in moderation.
Everything in moderation, and that pertains to all things in life.
