Doesn't matter what I do for some reason Saturday's are always high and then I crash. I eat a bit of a different breakfast on Saturdays but even if I eat my week day norm that doesn't help. This morning I set a temp basal rate of 40% and thought I'd be good. As you can see I was wrong. I've never worked out before at close to 300 but decided to give a correction bolus and do my normal routine. Yup, this happened. From 300 to below 100 in less than an hour. I felt gross.
