From my point of view side effects of concern are behavioural, cognitive and, electromagnetic (this seems to influence others intuitive responses to me - given mt2 effects signalling; I have no further insights as to how specifically it implicates the CNS in this capacity).
Electromagnetic could also be interpreted as "vibe", "lifeforce", "chi" even - laughably, but that's what it's known as in T.C.M.
Basically the "vibration" of the CNS electrical activity, that is what others "intuitively" respond to - and it essentially defines us, who we are, personality, social/emotional/behavioral state.
MT2 negatively impacts that in my case, and therefore the interpersonal responses I get become comprised - from irate, aversion, weariness, unsettled etc., tends to be reflexive responses of others to me.
It's also dose dependent, i..e. those responses were much more evident at 1000 mcg than 250 mcg.

I could get back to specifics a little later.
