Hello stremel,
It seems clear that 4 units of insulin is not enough to reduce your blood sugar but I wouldn't suggest you increase your insulin by yourself. You should make another appointment to see your doctor to set up a plan to increase your insulin. It can be a bit tricky as you can only increase the dose a small amount each day, but your doctor should be able to provide you with a plan that will safely meet your insulin needs. I wish you the best, and hope you get well soon!

Did the MD tell you how to titrate your insulin? We cant tell you how much to take! For 1 thing you dont say what insulin your on (different insulin's have different onset times, duration and strength) Not to mention that everybody needs different amounts. What I take for insulin would Kill others.
You do say you eat oatmeal Oatmeal is a carbohydrate, carbs raise BG ALL carbs raise BG. eat less carbs have less BG rise need less insulin.
Carbs include but not limited to wheat, rice, potato, pasta, most fruit, BREAD.
