I don't have any advice as to what you, personally, should be doing. But I do know that sugar is an issue for me and is a factor in my bipolar episodes. I haven't figured out yet whether my bp cycles affect my cravings for sugar, which leads me to eat more of it, which them becomes a cycle of it's own - or if I lose track of how much I'm eating, then get into the cycle of having too much sugar, which then triggers a bp episode. I don't know where the cause/effect begin and end. I know when I get a handle on it, though, it improves my ability to cope with the bp episodes.

I do find that if I eat the right kinds of carbs (oatmeal for breakfast is one reliable one, even though it's not my favorite), I crave less of everything throughout the day, and don't turn to sugar as much for the quick energy fix. I also feel better the more vegetables I eat, so I try to incorporate them into more meals (loads of sauteed veggies in a morning egg scramble, for example).

Hope you find a plan that works for you...
