Ferdinand,
Welcome home from your last day of the hell you used to call work. Things are looking up already. Good luck with the GBS. I've known a lot of people who have gone through that, and they will tell you it's all about lifestyle changes and physical exercise accompanying the GB. I have a feeling you're not going to be smoking for a few months, it will probably hurt your belly. But don't be discouraged, it will let your sticks get some extra aged on them.
Anyway, prayers go up for you bro...
