Last night just before I went to bed after a completely typical day, which included a 3 mile walk at 8am, I felt light headed so checked my sugar levels and I was at 4.1. I am normally high 5s before bed and feeling this was too low for bed I had a couple of biscuits and rechecked 30 minutes later and I was down to 3.4 and feeling it. So I had 3 dextrose tablets and 30 minutes later was back to 4.1 so followed it with a slice of bread and some cheese and went up to 8.9 30 minutes later. I followed this by testing at 1 and 3 in the night with readings at 4.9 and 4.7.
Now the thing is that as I have mentioned elsewhere I am in the honeymoon phase and was taken off of insulin (twice a day regime) and put on Metformin after only a couple of weeks as my DNS was concerned about the mid morning hypos I was getting and because my levels had returned to normal. So why would I suddenly have a hypo late at night about 4 hours after I had eaten my evening meal?
