A packet of crisps and nuts would not 'work immediately'.
I like your story but this part of it is simply not true.
Dodger, I can assure you by the time he had had his g & S and snack, he was able to discuss how his behaviour had impacted on the staff ie how loud had he been speaking etc
He even, in hypo, had a bead of sweat that appeared between his eyebrows(this was my way of realising it was a hypo) and even that receded as we stood at the bar.
It took a wee while, including a stay in hospital to obtain his 24 hour readings, to get his dosage correct but that made him OK again.
Now you have every right to disbelieve me but it would be a strange thing to make up about a subject that is very dear to me.
I bet I have collected more BDA tins than most people!!
Crisps and nuts are very slow acting so to try and treat a hypo with these is foolhardy as is trying to treat it with chocolate,yes it may bring him back to where he needs to be eventually but it will take a long time in comparison to what he needs to be treating himself with.One of the biggest misconceptions is that chocolate is good for treating hypos.........it is not.I am sure our resident doctor Ethan will back up my claims to be correct.That said some of the doctors I have met have a shockingly bad knowledge of the condition.
