Hi again
Thanks for all the responses. I had some Lucozade and that got me back up to 5. something then I went to sleep. But I am confused as to why I would go to 3.8 in the first place, as I had been eating snacks all evening, in fact my last food and drink was 11pm-ish, including a mini chocolate cheesecake, several bags of crisps, half a small bottle of lucozade and a piece of swiss roll and I was around 7.4 when I went to bed at midnight, only to start feeling like **** a short while later. How could this happen?
That was all **** food I know, but after tea I was still starving and just could not stop eating and was ravenously craving sweet things for some reason.
Also, I checked the metre readings several times and the metre was properly calibrated.
