Apparently it helps if you chew gum, whistle or have a candle next to you while you work. I have yet to try these though, the last time I tried it affected me so bad i couldn't open my eyes and they still had a subtle pain/that feeling the next day. This happened at home but strangely it never affected me when I was working in the ventilated hospitality kitchen at school.

Ugh I ate getting garlic on my hands, we have a garlic crusher so there's little touching but when I did hospo at school we were always using crushed garlic and then having to use computers for the next lesson so my laptop ended up smelling like garlic for at least a week.
