Woke up with a headache this morning, not having consumed
any contraband yesterday (Oranges plus the Three Cs, coffee, chocolate
and cheese are my migraine triggers) and decided it must have been
the unventilated act of soldering in a confined space, all because
I couldn't be bothered to extract the 12V fan that I keep to waft the fumes
away.


Is this a common or well-known problem?
