Tea or coffee?
Nothing will stop me from my morning cup of coffee - I generally have half a cup about an hour later then that's it. No more caffeine that day.
I've found, though, that tea suits me in this warm weather; it seems to be more refreshing and I was never a tea drinker previously, always coffee for me.
So I'm going to be drinking tea more often - it has around half the level of caffeine that coffee does so I could drink around 3 cups a day, perhaps adding one in the evening,
