Hi
I actually use a Dual Wave. I think either method is fine. But, for the most part when I bolus I take about 80% of the insulin upfront and spread the remaining 20% over 30 or 60 mins. This all depends on what I eat of course. As for insulin, I am using Novolog (basically Humalog). I haven't taken R for 10-15 years. It just works too slow to bring my BS down to normal levels. I am impatient and want it down as quick as possible to the 85-95 range. As I mentioned before, I go for walks to get my BS down quicker. I am on a ~150 carb/day diet. As Gerri mentions, Regular is likely good for gastroparesis. But, I don't have that (at least not that I know of). I would think for that a dual wave or square wave with a longer duration would fix that problem. Ken
