Tea - black, green, white or herbal - is one of life's precious things. It allows you to relax, chillax, refresh and be revived. It encourages a conversation and openness in a way that water, soft drink or coffee never can do. It is a joy to sip and savour. It is one of my favourite moments in life.

THE QUESTION IN FULL

Q. What's the difference between green tea and black tea? And can I drink green tea at night when I don't want caffeine?

A. Both green and black tea come from the leaves of the Camellia sinensis tea bush. Whether these tea leaves end up green or black depends on how they are processed.

A. If  you're having trouble sleeping or experiencing an upset stomach (acidity,  indigestion), headaches, shakiness or palpitations (coffee 'jitters'), then  excess caffeine could well be the reason.

Are you overdoing the caffeine? Do you live from coffee to coffee? Do you find it difficult to get going in the morning without your java fix? Sipping a cappuccino or a short black is a common way for busy people to recharge their batteries or even wake up in the morn. But what do you do when it gets too much? And what is too much? Read on for my answers.

Love coffee? Can't get going in the morning without your java fix? Sipping a short black or espresso is a common way for busy people to recharge their batteries or get through their workload but how much is too much? What are the tell-tale symptoms that you're overdoing caffeine?

There's nothing as refreshing and relaxing as a cup of tea. It's my favourite hot drink by a long way and one I look forward to every day. I drink almost every type of tea there is. English Breakfast with milk is my favourite but I'm also partial to a delicate Ceylon and most things herbal like lemon and ginger or anything with a little peppermint. The only tea I'm not fond of is Earl Grey.

I like to sip this iced tea as a refreshing not-overly-sweet drink. It’s pleasant and sweet without being sickly-sweet. It’s not fizzy so there’s no gaseous feeling nor burping afterwards. But how much healthier is it really?
