I am so glad for this site!! I remember reading here about people experiencing rebounds. I hadn't had any problems like that so I read it but didn't have to put it into practice. Well, that changed. For about 3 nights Kylie was in the 400s!! at our 11 pm check. In each of the cases I was pretty confident that it wasn't the bolus from the bedtime snack so I figured it must be the basal. I went to up her basal, but decided to do a basal review first. I found that from 8:30-midnight she had the highest basal of all day. Hmm... I thought. Could this be a rebound? I decided to check it out. I lowered her basal instead of raising it. Guess what? It worked!!! Her 11 pm # was in the 100s that night and the low 200s the next (we had trick or treating that night, so I wasn't alarmed!). I NEVER would have known about rebounds if I hadn't learned it here. (My endo's office has never uttered the word "rebound" ever.) THANK YOU ALL for sharing your wisdom and experiences!
