Golly, Miss S, I thought I'd already mentioned that you're describing one of the classic groups of symptoms of reactive hypoglycemia coupled with low adrenals. These are the most important points for most people like this. Liver/GB and thyroid also can play a major or a minor role, depending on the person. Please re-read my post to you on these issues if you're still suffering. If you can't find it let me know and I'll try to repost.
One of the elements of Chinese Bitters is rumored to pull down blood Sugar in at least some people, so I would whole-heartedly agree with Paulette on eliminating any unnecessary supplements. Also, other supplements you may be taking could have potato or rice starch, etc. as fillers, which can negatively affect your blood sugar, so be careful. Chromium can also be bad, although many books say that it is good.
