The first time I had two pints of beer in my late teens I was horribly sick. Now I can drink two pints of beer without feeling any ill effects.What is the mechanism by which our bodies become tolerant to alcohol, or indeed other drugs, all of which have a smaller and smaller effect with regular use?After all, I am consuming exactly the same amount of poison which made me ill 30 years ago - why doesn't my body just do what it did back then?
