Thanks for that - I really just wanted to know about lozenges. We are lucky enough to be going to Stratford upon Avon next week for three plays, and if I end up with one of those annoying coughs that hang on after colds, I need something in my handbag to prevent being murdered by irate fellow play goers (not to mention the actors as we are near the stage).
Have now got some sugar free Strepsils - so those plus a bottle of water should do just fine.
Best wishes
