Well done, especially after finding the beer. That was almost too creepy for coincidence.
You'll be fine. You seem a very strong person. It's not unusual for your body to rebel for a while with feeling sick etc. And yes drinking lots of coffee doesn't help, I know cause I'm a coffee freak. BTW tomorrow morning I expect the end of the story. You can't do this to us. Start a good one and then it's 'to be continued'. That's like good television.
Take it easy, keep posting and maybe you should buy your cigarettes somewhere else for while. Just a suggestion.
