I've found that CA gives me some pretty nasty 'allergy' symptoms. Just like getting a bad cold. Usually isn't a problem with adequate ventilation and if I use it sparingly. I also found that using accellerator made the whole problem worse.
Now I use liquid Ambroid Pro-Weld (or something similar) as much as possible. I still use CA, but nowhere near as much as I used to. It's a good thing, because I prefer the Ambroid now that I've used it more.
I also find that I'm using epoxy more than I used to.
