I'm sure here is plenty more I eat and drink that has shite in it.... I used to drink pepsi ALOT even to point of takin a gless to bed for in the middle of the night, then my wife joked i was becoming like a drug addict with it, and after thinkin about it she wasn't far off so I pretty much stopped.

I have the odd can, and if I do drink a cola based drink it's full fat Pepsi, but if a drink a couple of cans a week i'm doing well. So I dont think it'll bother me much.
