I have a packet of Boots "Sore Throat Relief Dual Action Lozenges" on my desk. They contain (Hexylresorcinol) an antiseptic and local anaesthetic. They are really good.
I have always found Lockets and Soothers a bit pants.
That spray off the ad with the green dragon...cant remember the name but tried the stuff once and its fkg fantastic
my mum uses one called difflam spray cos its prob cheaper but works just as good
