Re: ???rapid and long lasting insulin---samqkitty----
They are used in combination. Your body needs insulin for metabolic functioning even if you don't eat. The long-acting insulin is used for this purpose.
The short-acting insulin is used to cover the carbs when you eat. You usually have to learn to count the carbs in your food, a task that sounds difficult but actually just has a bit of a learning curve. Then, you have an insulin to carb ratio. For example, my insulin to carb ratio is 1:10, so for every 10 grams of carbs I'll be eating, I need one unit of insulin. After a while of counting carbs, you end up memorizing the carb content of foods you eat regularly, such as whatever bread you normally use, or whatever fruits you like (one apple +15 g, one slice of the whole wheat bread I use is 15 g)...and you just add up the carbs for your meal, divide by your ratio, and that's how many units of rapid-acting to take.
For combination foods (like stews, salads, etc.), you'll get used to estimating after a while.
As for taking rapid before meals and no long-acting, I don't think that's possible, but I'm willing to bet that if you start taking rapid for your meals, you'll need a lot less of the levemir. I think part of the problem for you, twokatss, is that they've been trying to use the levemir to cover ALL your insulin needs, and that's just a lousy way to do it, IMHO.
