I just did a buttermilk test.

Once I felt good, and no buttermilk for a day or two, added 1/2 cup at yesterdays lunch. ( otherwise only eggs,and steak and salt) . By bedtime congestion was setting in. Horrible night sleeping, or not sleeping. Mouth breathing. Trying to maintain more upright position. Lots of sliding down and pushing back up to near sitting position.


Otherwise my brain is more lucid than I expected for such poor sleep. Likely a few days on meats is helping ketone levels.
Buttermilk is not good for me.
