I apologize for this being somewhat verbose, I wanted to summarize the past 3 days since my dental procedure apparently affected my ketosis similarly to alcohol (per @carolT linked below). In my case, though, the anesthesia appears to have take 48 hours to get removed completely, and then the better part of another 24 hours for my ketosis to return to normal again. If anyone else has had a similar experience please post in the other topic linked below. Thanks.

Within an hour of completion of the dental procedure, my BrAce dropped lower than my normal range and stayed at the lower range for the next 48 hours - Jun 1 at 2 pm. It has gone up again to my normal range, but I had to give it some help by eating raw ginger last night before going to bed and eating some coconut oil today at work.
And as of this morning, BrAce appears to back to normal again.
I just tested urine again, Jun 02::2:30 pm and matched 1.5 mmol/L.
