As Of A Week Ago, For Every Time I Had

As of a week ago, for every time I had something with sugar. It would give me horrible shakes. Is that reactive hypoglycemia? Since that day, I now have to eat every 3 hours or the shakes will set in. I stay away from sugar, white rice, and all refined stuff. I've been taking chromium, and that's been making me better where I am able to hold off on food for long periods.
