Soft - Good old diet Coke (or Diet Pepsi, not fussed)
Particularly like tap water at this time of the year cos it i is so cold and refreshing.
Alcohol - Rum or bacardi with coke/ larger/tia maria/baileys/wine/lovely Pmms/ ... actually anything apart from Whiskey, Brandy or Vodka.
Whats more I have a bad habit of mixing my drinks, however I tend not to drink too much these days, can't cope with the hang overs!
