My father used to have very low blood pressure. As per his doctor orders (seriously), he kept a bottle of gin in the fridge, for when his blood pressure dropped.
At the time, I kept an old bottle of gin, without the label, always full of water, in the same fridge. Since he almost never drank the gin, his bottle was always in the back of the fridge.
One day, I went to the fridge, got the bottle, and started chugging from it. Must have rank about 10 or 15 ounces before the taste kicked in.
From that day on, I've never again used a gin bottle for my water...
