Sugrkiss,
I know how you feel. This disease is hard but add three kids and a husband to the mix and it sometimes becomes overwhelming! My husband is so darn understanding that it makes it a whole lot easier. My kiddies sometimes take better care of me than I of them. I totally relate to the whole body change thing, prednisone is a double edged sword isn't it?
About the smoking thing, all I can say is I think that is the best thing you could ever do for yourself is to quit. I imagine that it is going to be difficult but you have all of our support.
Take care ~ Melanie
