You can pick up to six of these so time them well, and remember don't drink more than three units of alcohol per day.

Two biscuits, one pack of low-fat crisps/savoury snacks, one French fancy or a two fingered Kit Kat.

How about a small glass of dry white or red wine, or even champagne (they're all one and a half units each). If you're more inclined to spirits you can have two measures of vodka, gin, rum or whiskey with a calorie free mixer (roughly one unit per measure). Half a pint of lager or cider will have the same effect.

You can also go three handfulls of popcorn, a skinny cappuccino, two squares of chocolate or ten Malteasers. What'll it be?
