So I didn't have an especially wild New Year's Eve. I didn't drink any alcohol. I ate dinner at about 8pm and went to bed at about 10pm. I was low-ish going to bed, but I'd had a cup of tea and some clotted cream just before going to bed and assumed that would keep me bumped up through the night (rock n roll). I woke up at about 3am. My dexcom was alarming, and saying I was low (under 2.2) but I'm not very good at waking up to the alarms. I had woken up because I had touched something damp in my bed, when I turned the lamp on there was a very copious amount of my partially digested dinner vomitted up over my bed. I do not remember being sick, I did not feel like I had been sick - no burnt throat, no horrible taste - but it was definitely my dinner (gross). I'm not sure if I was sick while I was asleep? I feel like that would have woken a sleeping person up. Or if I was sick while hypo unconcious, I didn't test in the night when I woke up because there was a lot of vomit around my bedside table and I was awake and able to walk around, find bin bags & antibacterial wipes, so I figured I was fine. I gave up trying to clean the vomit carnage - I had a washing machine full of clean washing and it was 3:30am - and went to sleep on the sofa, when I tested at 7:20am it just said low which is under 1 on the omnipod. So I think I probably was fully unconcious and that's why I didn't notice being sick. I naturally sleep in the recovery position, self preservation is important, but I feel like vomiting while unconcious is really quite a significant escalation of the risk scale. I don't really want to die by choking on my own vom while unconcious. I'm not really sure why I was sick, it wasn't a sick inducing meal, it wasn't seafood or anything exotic. I have had hypos with a really helpful severe nausea symptom, but even when I've had that as a hypo symptom I've never had a hypo that actually made me throw up. TLDR: Will low blood sugar make you spontaneously vom? I'm totally fine, I've had breakfast, I've not had a bolus. I'm 5.1. I'm really not looking forward to attempting to complete the clean up - it wasn't a large dinner, but apparently partially digesting it really significantly increases the volume. So I go from feeling totally fine and not sick to having to clean up the mysteriously appearing vom and then I feel grossed out sick! Eww.
