Type 1 Any theories on almost fainting episode?

Had an odd experience on public transport this morning. I caught the train around 7, feeling fine. After about 20 minutes I started feeling really sick all of a sudden, just before my stop I was convinced I would throw up before I could get off. I stumbled off, felt very dizzy and my vision went black for a second. I sat down and quickly came around.

That morning I had woken up with a bgl of around 16 (I generally don't experience any serious physical issues other than dry mouth, etc. when my bgls are this high), I corrected and just after this event, tested at 5.8 with 2.6 units of active insulin. I'm wondering if this (+ being diabetic - although this hasn't happened to me before) could have anything to do with this, or if anyone has any other theories that explain instances of nearly passing out/sickness like this?
 
I don't know how much time elapsed between testing at 16 and then 5.8, but that sounds like one huge drop in a small space of time. This could be the cause, big fast drops after insulin do make me feel quite uncomfortable. Biggest drop I had made me feel sick to my stomach and I did throw up from it.

Normally I'd say that you had a hypo, though the 5.8 suggests possibly not. Two possibilities that I can think of
1) You did have a hypo which was corrected by a liver dump.
2) False hypo if you've been used to running high.

How long have you been diabetic? Do you get good hypo warnings?
 

I've been a diabetic for 6 years - my hypo warnings are pretty good, and I have been running a bit high recently so that's a possibility. It was just odd as I've never experienced anything like that before.
 
Theory number 3: it has nothing to do with diabetes.
It is very easy to blame diabetes for everything but sometimes it is something else - what you ate, travel sickness, ...

Look after yourself, take extra BG readings and don't over exert yourself.
 
Might have nothing to do with diabetes.

But if you dropped from 16 to 5 in a short period of time, it could be that your body was just overwhelmed with it all.
