I thought this might be topical with the holidays fast approaching

As I get older, I find that I'm much less tolerant of substances that might have mood altering affects. Sugar is one such animal, but I find that I crave it - to the point that I'll completely forget what it does to my body. After the brief high, I get a huge crash and then suffer through crankiness that is proportional to the amount of sugar (almost always chocolate..sigh) that I've ingested. Simple carbs do the same thing but not as dramatically as chocolate. I'm also becoming intolerant of gluten (irritable bowel) but that's another story.

Does anybody else have this? How do you get through the cravings? Yesterday at the grocery store, I put a small chocolate bar in my cart & was eating it on the way home having totally forgotten what it does to me! It was when I felt the sugar rush that I realized what I'd done.
