I like spicy but not really hot things, jalapenos I slice them and don't eat them whole, and stay away from anything hotter. Pretty spicy is fine for me but not just hot where it just burns. No stomach problems just mouth burning and numb I skip.
It's a bad habit, not even counting the mwm bass bins I did 3 other subs designed like the 1502/1802. With two of them, I used a car type sprayer, one to add clear, mine and a friends which was painted on the inside. This made a few fumes but the worst was one I did in Florida. We went down to Palm Beach and I couldn't haul a compressor and everything to go with it and he wanted it black on the inside. So I just used a bunch of spray cans to get the inside black, spray cans are the worst for fumes. Luckily he wanted the outside stained and clear but spraying the inside was bad.
I had a respirator but it turned out to be somehow clogged and all I had was the little paper mask, never again.
