Today i took 500 mg niacin during the day instead of right before bed so i could take postprandiol blood glucose and ketone readings and here they are: also i have no 'noticeable' flushing when i take niacin right before going to bed but the flushing today was extreme and painful and lasted over an hour. The things we do for science?

1 hour bg 97, ketones 1.7
2 hour bg 101 k .9
3 hour bg 95 k 2.2
