I had one booster put me in bed, but no lingering symptoms until after my mild bout of covid. I still have symptoms that I can’t seem to shake, but have run out of options. I’ll continue mega dosing my B12, focusing on high nutrition, fitness, exercise, good BS management, etc. Returning to neurologist in 4 months.

I think I had an ENA. Will have to check. ………Yes, I had the ENA series and was .2 across the board! I’m very pleased with that.
