what sort of food are you eating before the hypo? if i have say a small piece of dairy milk i go high then go very low 1hour after. Also if i have to much fat and not enough carb the fat makes me go very low. Also if i exercise vigoursly when im low carbing as in not enough carb to compensate the energy im using up. you need to trace back what you ate or did 2hrs before the hypo. im not on meds so it may be as simple as adjusting them, someone will be along in a minute to advise on that score
