A lot of the herbs mentioned here (gymnema and bitter melon specifically...not sure about the rest) are constipating for me. I've tried gymnema three or four different times. I do not want to go down that road again. But on a good note they did lower my blood sugar. So what is one to do? So far low carbing is working. Keeping my blood sugar under 95. Would be nice if I could tolerate a few more grams of carbs though! IMJUSTSAYING
