I know a couple of you have explained this before, but for some reason I can't find the posts. Coco switched to Lantus last week due to extended disconnects for Basketball. We started her on 37 units and she hit the high 300 and 400's everyday - multiple times. She says she never felt low. She started dropping overnight, so I lowered her Lantus - now her BS is in range... I hate to think of her being in a constant state of rebound for week and I remember another explanation for it...just wondering what that other explanation was.
