I've always quite enjoyed the odd cup of tea now and again but in the past couple of weeks I seem to have acquired a rather ferocious addiction. I used to love a pot of camomile or lemon grass - and for a caffeine hit a dainty wee espresso would do the job. Now none of that is enough. I can almost audibly hear my belly demanding more tea. Proper tetley's tea with milk no less. And a biscuit.
