I don't drink much alcohol (just the odd glass of wine at Christmas or when dining at a restaurant) but I do drink copious quantities of diet coke. Ever since my Uni days I've consumed several litres a day. Aside from wanting to cut down or eliminate this completely for my health, it also isn't very good for my wallet. Until recently diet coke typically cost around $2.40 for a 2L bottle, and I could stock up when it was on "special" for $1.69. However, it seems that Coca-cola has increased the wholesale price of their range (their excuse was increased sugar prices - which doesn't really make sense for "diet" coke!). All the major supermarket chains in Sydney have raised the regular price to around $3.30 for a 2L bottle, with the price on "special" only dropping to $2.49 these days. Even buying only on special this means that the cost has gone up by 50%, which will cost me around $600 extra each year. Time I tried to quit drinking diet coke "cold turkey" and switch to just drinking filtered tap water and the occasional cup of tea.
