Basal = long acting insulin i.e. levimir
Bolus = short term acting insulin i.e. novorapid
Firstly start with your basal, do basal testing by skipping breakfast and testing every hour. Watch trends and adjust basal dose accordingly. Then start carb counting get a correction factor and a Insulin to carb ratio, then you add carb totals for a meal and inject accordingly. Testing I:C ratio requires testing 2,3,6 hours later and watching for trends. Its effort to start with but once you have your basal sorted and a good bolus I:C it all becomes easier.
Complications are nasty including going blind and losing your limbs. It’s a time bomb waiting to explode and you won't see any signs until it is too late. Don't wait for it to happen make a difference now, its never to late to undo some of the damage done.
Heathly diet = little bit of everything, including the green stuff. Look into glycemic load and Glycemic Index (GI), these give a good indicator to how much a food will effect your bg. Carb quantities are not the only factor when it comes to raising your bg for example a simple carb such as ice scream will have a high GI and give you a spike, this spike might be useful if you are low or are playing a strenuous sport. Complex carbs such a noodles will have a lower GI and give you less of a spike however it will keep working for hours after consumption. This would be a good food to eat before a sport or at a main meal to maintain bgs through the night.
Standard Deviation is a important as it has been proven to that the smaller your SD the less chance of getting complications, it is easier to stay in a narrow bg band than it is to stay in a much larger band. Reducing bg spikes will help you lower your A1c and reduce your SD.
