I have had diabetes for coming up on two years now and am lately having trouble keeping my levels under control. Usually when I have a meal and give myself the correct dosage(ratio is 1 unit to 15 carbs: have been using that since diagnosis) I can go low approx 3-4 hours after the meal but at 2-3 hours after my BGs are usually in the 5-10 range. If I lower my insulin I can get many different results depending on what I eat. I am just wodering if there is a way to figure out my insulin to carb ratio and if I should be back to pre-meal levels at 4 hours or 2 hours.
Thanks
