FQ,
The question is whether you should carry while on medications or not.
I have been known to take codine and morphine on ocsasion, and I would not touch a gun while on that stuff. Damn, I can't find my ass with both hands on that stuff. When I take my muscle relaxers I don't carry, because one of those little yellow flakes has the same affect as several stiff ones. However, when I take sinus stuff or cold syrup I feel competent, but I would hate to have to explain myself in court if I used the gun at those times.
