...Then I went to a meeting this morning and the only drinks on offer were tea and coffee in flasks. No water and certainly no decaf.
Eventually I put a dribble of coffee in the bottom of a cup, topped up with milk and stirred in some sugar - to make a kind of milk shake. It's the first time I've knowingly consumed caffeine in a year, even if a small amount.
My throat started closing almost immediately. Hours later, after taking Singulair, my throat is still sore so I don't know whether it's the caffeine or flu.
