Have you noticed yourself feeling kinda high from working with oil paints and the related solvents?
Seriously, most of that stuff is toxic and you should invest in a nice, lightweight and comfortable organic vapors mask.
I use this but it is overkill:
(except mine if from 1972 I think).
Ever noticed how in stories about famous oil painters some of them have a crazy streak? Anyway dude, keep up the painting.
