We have a beach vacation coming up and I know he'd rather leave his pump in the house while swimming/sand/whatever. However he has such a strong dawn phenom I hate to switch totally to lantus. Anyone do a combo type thing, I was thinking of some lantus, keeping a site in for food/bolus, but then hooking up again at night for a little basal support. Is this a crazy idea? If anyone has done this or has any input, how on earth do you start to figure out how much to lower the basal at night to cover those early morning spikes he has. How much lantus to give to cover days? I realize he'll need corrections during the day, but figure the beach activity will help with that too. Any help appreciated.
