Hi, I have been there, but it does state that we should have a quick acting first and then slow release carb food. But I don't, as it is far too much for me and sends me soaring, we are all so different which includes our tolerance to foods for hypo's, our lifestyles, weight, build, time of day etc. 3.4 isn't critically low, but the amount of correcting foods does look far too much. Has he spoken to his DSN for some help and advice, as he might need to alter his Insulin dose. Could he join the the forum, as I'm sure he would really benefit from being with other people with diabetes, as we try to help and support each other as much as possible, which is half the battle.
Best wishes RRB
