First off, take a day off work, sort out a doctor and a diabetic specialist. There's no excuse for that, unless you're very well controlled (which you're obviously not).
What you haven't said on here is what type of diabetes you have, and what your treatment is?
As for the whole side of your body not being usable - I've had this happen once, when I was 19, after a *VERY* bad hypo (that required my parents to sort me out). I was hospitalised, and couldn't move one side of my body or say anything other than 'Yes' and 'No' for 2 days. My speech returned (slurred) after that point, but took a few more days to return to normal. Was practically like having a stroke.
In other words, it's unusual, but not the end of the world.
As for the other things you're reporting - it's much better to be marginally higher at night than it is to worry about keeping your blood sugars low. If you have a hypo during the night, in my opinion, you shouldn't just have the standard 15 carbs to sort yourself out, you should have 30 carbs minimum. The logic behind this is that it's much easier for you to mentally deal with high blood sugar than it is to deal with low blood sugar while you're sleeping. If you have 30, then find yourself getting up to go to the bathroom during the night, test again, and correct your reading with insulin according to your standard level of correcting.
I've always done this, and my HBA1c is 6.2.
DON'T leave yourself at risk of further hypos when you're asleep - this is MUCH WORSE than being slightly higher for the remaining hours of the night.
