Yes, I think splitting your morning Metformin dose is worth trying - have one with breakfast, and the second with your lunch.
Does your doctor know you are frequently/regularly having hypos? Anyone can have a hypo, of course, diabetic or not, but I don't think they are very common with us Type 2s. I've never had one, but then I was diagnosed at an early stage and still have good pancreas and liver function - or so it seems! (touch wood :wink: ) Maybe ask him/her if you should be having so many hypos.
What do you eat for breakfast? I have a 2-egg omelette every day, which easily sees me through until lunch. Protein releases glucose much more slowly than carbs, which might even you out a bit better.
