very possibly the molybdenum. i had severe memory deficits after a terrible infectious disease with biofilms -- treated myself with the bioactive b12's i need according to my specific genetic mutations, recovered to about 75 percent, but still had the big gray screen in front of what used to be a versatile and highly active mind. it was destroying my days. took molybdenum for the first time, and within 45 minutes that gray screen was gone! and oddly, the constant ache in my arms, from wrist to elbow, vanished, too. then i began to take the molybdenum every evening, and an hour later used activated charcoal -- a whole tablespoon, mixed with water. i hope your recovery is still going well!
