I have drank guinness every single night for the past 5 years!!!! I have about 8 to 10 cans a night at 440ml so its around 7 pints on average!! No hangovers, no ill health and I am 5ft 10 and 10 stone !!! I do not drink anything else as it sends me nuts or gives me the hangover from hell!!! Oh yes I am now 41 and only started drinking at 35!! Lifes fun!!!
