I've been pumping since May of 2002. Four years with the MM508 and three years with the MM515. Both pumps have the dual wave bolus feature, I really never use this feature unless there is a high fat content food that I am going to oink out on (the pizza bolus, etc etc...). A few weeks ago, I read a forum post where a TU member stated her pump educator recommended using the dual wave bolus setting for every meal. Her pump educator called the normal bolus a "skittle" bolus, fast acting sugar bolus. Since all of my meals do not contain "skittles" it only made sense to stretch out the bolus time thus giving myself more units over a longer period of time. After reading the TU forum post, I have began using the dual wave bolus for every meal. My numbers have been excellent the entire time. I have dropped my average on my blood sugar meter 15 points. Anyone else use the dual wave bolus at every meal?
