I got sick just after quitting as well. It was almost instant - the next morning my throat hurt and by the next day I was coughing, runny nose, and couldn't breathe. It was terrible but I think it actually helped me out. I felt so shitty I didn't stay out at the bars very long and made it through my first weekend ever without a smoke. I'm still a little congested but it doesn't last forever.

Just push past the cold.

I can't give much advice on how to avoid smoking while drinking - every time I have tried to quit a night of drinking is what has done me in. What I plan to do is keep myself busy, drink less and stay out of bars that allow smoking inside.
