Crashing Fast?

Around 10:00 last night my son came rushing out of his room heading for the kitchen saying that he felt like he was crashing-he’s only did this one other time since his Oct 09 diagnosis his BS then was 54 and already showed signs of a mild hypo. He is still honeymooning which has been very difficult because we dont know how much insulin he’s actually gonna push out on his own.. he has had no insulin for weeks now-He tests about 7-8 times a day averages 110 in the am typically goes to the 60-70’s mid morning and then peaks at around 150 after lunch and dinner. He was 157 before 6:00 dinner with no insulin as he was only having a 10 carb chicken/veggie burrito- as we are early in his diagnosis we were told to use a 120 average at a 40-1 carb ratio.. he usually has a snack after dinner but didnt last night; not snacking is what brought this on I’m sure.. He knows that he is supposed to treat, test and then eat- but.. he tested 1st @ 72…he was in a bit of a panic and immediately drank a bottled water.. hmm.. However, he really seemed ok; Obviously I told him that water would not help a low and gave him a bit of OJ and he ate a light wheat sugar free PBJ sandwich (a part of his daily life now), he has been at 60 before with no symptoms so I was not overly concerned at this point with a 72 but after the ate he immediately started to show classic signs of a low-confused, totally spaced out, feeling extremely heavy to the point he could’nt move, his pupils were huge and he was very pale but no sweating: I retested and he was 96.. I even set up a different meter and tested he was 116 and still just totally whacked out of it.. Then as quickly as it came on it was like magic his color came back and he was back to normal.. he did have a few small red bumps pop up on his palms… hmmm.. they are gone this morning. Any ideas as to what the heck happened here??? Now I’m totally paranoid to leave him alone.. what if he gets confused again and drinks water???:dontknow: We have a endo apt early Jan. Not sure if a pump would help at this point.. Mom would sincerely appreciate any input from you guys…
