A friend who drinks, a lot, has been round my house recently and I had to open all windows, burn entire collection of scented candles after they left. Not an alcohol smell, but a kind of sweet, sickly, all-pervading aroma that seems to stick to your clothes, and is really, really unpleasant. I do drink myself, not to excess, but have never come across this before. Am I being weird or is this common?
