Men are advised to drink no more than four units a day - the equivalent of two pints of regular-strength beer, and women no more than three units - the equivalent of a large, 250ml glass of wine ( I am not telling anyone to drink).

Toilet trips-many people did not know that the dehydration caused by drinking could interfere with their sleep. Alcohol stops the brain from releasing vasopressin, a chemical which tells the kidneys to reabsorb water that would otherwise end up in the bladder. Without this signal, the drinker needs more frequent trips to the toilet.

The loss of this water can also lead to a headache emanating from the inner lining of the skull.

After drinking the body tends to fall straight into a deep sleep, and only enters the REM stage once the alcohol has been metabolised.

As the body wakes more easily from REM sleep, many drinkers find they stir early in the morning without feeling as if they have slept properly.
