Hi Lyn, we need more info really before we can advise but if you can't go to bed less than 10 without waking up with a hypo then you're probably taking too much insulin. I've said this many times but it's true, diabetes doesn't cause hypo's, it raises your BG levels. Hypo's occur in the vast majority of times due to over medication. Keep a diary of insulin, BG levels, food etc for a couple of weeks. Either post some results here or speak to your doc/nurse.
Eating late suppers and having to inject for it will only make matters worse long term. You'll end up putting on weight and needing more insulin due to resistance. Good luck.
