Very true about the GABA inhibitory neurotransmitter being important. As for B12, the top ten B12 containing foods list reads like a menu of my most eaten things. Shellfish, liver, fish, octopus, fish eggs, lobster, lamb, beef, cheese, eggs. The only one I don't have in my fridge or pantry atm is lobster, seriously.
I appreciate your well informed input. Thank you.
