I found smoking dropped my blood sugar by 8 points- tested before and after a joint. I don't think that it is statistically significant. My neuropathy, however, has not progressed beyond numbness in my toes. Since I was diagnosed about 4 years ago, I would think that it would have progressed by now, but it hasn't. I did find that taking a mix of cinnamon, ginger, garlic and tummeric (four "0" sized capsules every night), lowers my blood sugar by about 20 points- yes, I tested it out by going a week without my spice. My blood sugar went back up to the 130-140 level, when before it was in the 110- 120s. I take my spice every day now. - Granny:hippy:
