@caledonia, @Star-Anise, @Freddd, @Critterina, @ahmo... Woohoo! I did it! I raised my b12 a bit yesterday (albeit kinda accidentally) and did not have a potassium crash! I tried a new seafood source, and, based on results, it has more b12 in it than the internet charts predict. I had a bit too much energy all day. I slept 10 hours though (wore myself out), so no insomnia. Helped perhaps by the 400mg selenium I took at bedtime. I also had WAY less inflammation. So, I am excited about progress!
