I have always been a coffee drinker - I would always rather have had coffee, any coffee, than tea (in fact, I'd rather have had dish-water than tea!). But recently, I've become fussy over coffee (I love freshly-ground espresso-based coffee, but have gone right off instant!) and developed a liking for tea - I now drink tea by preference where 'real' coffee is not available, or when I'm not sure what the coffee will be like.
I've not noticed any other major changes to my tastes, but the tea/coffee thing is really dramatic! Am I alone to experience this?
