Eoghan McDermott is back for the final part of this series looking at what happens to us when we drink. All very important to know but it's entertaining mainly due to the volunteers they've roped in to get drunk on screen. Last week we had ones throwing up, passing out, and there was almost fisticuffs between two young fellas - the drink lads, it's terrible stuff. More of the same tonight as they will examine the effects of hangovers and see how someone's emotional state is impacted when they are drunk. Ahh beer tears, no sadder sight.
