Cola Drains Muscle Power

Caffeine is supposed to pick you up, but this article on the BBC reports that too much cola (we´re talking three litres or more here) can lead to tiredness and even muscle paralysis. This is due to a drop in potassium levels in the blood, probably as a result of too much sugars and caffeine. Even caffeine free variants of soft-drinks can cause diarrhoea, so drink in moderation.
