I love tea - in most forms, whether "builder's", a nice mug of Lapsang Souchong (it's like having your own personal bonfire) or one of those pots of Gunpowder Green that gives you a buzz you're not entirely sure is legal. Boiled-up Indian chai (none of your chemically imitations) is great, as is the elusive, cardamom-infused Pakistani green tea that is similarly ubiquitous in its home country.

But I also love coffee.

What's gutting, however, is having caffeine as a migraine trigger...
