Anyone have any ideas on how much to drop the background insulin by. Van has 9 units Lantus morning and 8 at night. He is off to camp (with hubby) for 3-4 days and is a kid that goes low with exercise and that's what the whole thing will be. These also carry on over night and currently I'm not sure if he'll be sleeping in with hubby or in a dorm with kids. It may be that without the stress of school work he won't need much of an adjustment, school hols at the moment and he's gone up with his needs even though active. MAny thanks.
