I don,t mean to be harsh, but what in heavens name is the young man thinking of? First of all, he,s being foolish, no, he won,t always come back from a low on his own. Second, and most important, obviously he is taking way too much medicine for his food intake. Has he talked to his doctor about these frequent lows and thus adjusting his meds. I know what a low feels like, and it isn,t pleasant, I can,t imagine this boy having this many. There is no reason on earth he has to go through this, work with his health care professional , it,s just too much medicine that is bringing on the lows. Has he been to a dietician to help him learn how to eat right and how to adjust his meds according to how many carbs he is taking in a meal. These situations your son has can be so easily avoided with just the right adjustment of medicine and food. Good luck,
