Aside from the drink ban and all, I gotta say I don't think that sugar's good for you but its hard to resist.  About 6 months ago I stopped eating stuff with sugar as much as I could and also cut out pasta and bread.  This from a man who never met a donut he didn't like.  It actually wasn't that hard except that I have noticed that if I have a spoonfull of icecream one night the next day I'm craving something sweet.  I think its because your brain runs on sugar and it likes it.  The reason I stopped eating fast carbs was cause I noticed things like how a bowl of pasta just seemed to make room for more and how I would get hungry or lightheaded like my blood sugar was all over the place now I feel a lot better.  The first month I lost ten pounds, (im 6-0 175ish,) but that might be just muscle disappearing with age.  Don't take this as preaching just sharing my experience.  Still drinking beer but it has less effect than before.
