It sounds like you were overmethylating. I would try some flush inducing niacin to reduce your methyl levels. I (think) I was over-methylating myself, peeing a lot, rumination (rumination on terrible thoughts) and feeling just suppressed. I took some niacin, got a flush and things started getting massively better very quickly.
I do have to note, though, after these methyl groups are removed your serotonin and dopamine (and whatever other transmitters) should drastically drop (as overmethylaters have elevated transmitters beyond normal function) I wouldn’t expect a full mentality back quickly. It seemed like I had to go into the outside world and re-methylate certain areas through experience. Very anecdotal I know, but it has helped. Currently I take niacin (200mg) and a b-complex for the folate. I can say I feel much better. I’m sorry your protocol didn’t work out for you, but I’ve seen people have similar results to yours as they treated themselves for undermethtylation when they were overmethylating and gave themselves panic attacks.
