Sounds like it might be your system getting used to less sugar. Have you tried eating some of the angelfood cake in the evening when you tend to get lightheaded. I think it has lots of sugar. Also several small meals divided during the day might help. When I get lightheaded and nauseated from low blood sugar I usually eat a couple of tootsie rolls and that helps me.
Also, you might do a search on the web for low blood sugar and see if you can get any ideas from that.
