Many thanks indeed to all who replied. I have always been a little suspicious of paracetamol because it is fairly easy to overdose whereupon it kills by wrecking the liver. However in the doses recommended, it is perfectly all right - doesn`t really seem like a good idea, somehow.
It's not as hard to overdose as you might imagine, because it accumulates in the liver. Therefore if you keep taking it too frequently and in relatively small doses, you can accumulate enough to overdose without ever being aware of it.
