The smell of Epoxy will make me sick. Generally the day after I will have a killer headache. I cut way down on the use of epoxy. When I must use it, I glue what must be glued and get the heck out of there. And don't go back in there all day. IT only gets worse with time. One friend of mine actually would wear a filtered mask, the kind they use to paint cars. You know, with the two round filtered elements sticking out at angles. IF you ever get to that point, those masks do work.
