Yeast

... i seem to be allergic to yeast. When I avoid yeast, the hypoglycemia gets better, but my hypoglycemia is still bad. Avoiding yeast allows me to eat more than 15g of carbs a day! But now, when I eat too many carbs my body gets really really heavy feeling and my fingers and extremities start "tingling"... like when your foot falls asleep. what causes this???
