Sorry if I'm reading into this too much, but did the symptoms you described above ultimately lead to you abandoning veganism? Also, what were the dietary changes that caused those symptoms?
Yeah, I ended up abandoning veganism, because I no longer felt (and feel) the empathy that I did back in the day (if there's much left). Being able to experience the world through the lenses of someone with low empathy makes you a little sympathetic (heh) to those that are born like that. Basically my decisions are purely rational as of today. I'm lucky to not be impulsive at all; if I were, I would have fewer friends than I do.
I briefly answered the dietary changes in another comment.
