Sober, but I love tonic water that was called quinine tonic water when I was younger, but nowadays tonic water usually has little if any quinine, and citrus and high fructose corn syrup and/or sugar.
"Per FDA ruling, tonic water can contain only 83 milligrams of quinine per liter. The typical medicinal dosage of quinine is around 500 milligrams, and in the case of malaria, it is taken multiple times a day"
I lived in SE Asia for over 7 years with close to 2 years of living in remote areas with dengue and malaria. I drank my Schweppes tonic water because I am sober and enjoy the bitterness, and it gave me some peace of mind that I was keeping quinine in my system at any level.
Having cobra anti-venom was a lot more important where the nearest trauma center could be 12 hours away by vehicle due to winding, mountainous, and difficult roads before hitting a real paved road.
