LadySycamore's right--severe menstrual cramps could be a sign of something worse, like endometriosis. You should get that checked out to make sure it isn't something serious.
And as far as smoking, I smoke, and I intend to keep on smoking. It's one of the few pleasures in my life, and damn it all to hell, EVERYTHING will kill you eventually. Everything you enjoy turns out to be bad for you; I'm not a fast-food person, so I figure I'll keep my cigarettes. It can't be any worse for me than a big mac
