I've played with it on and off for years from 1mg up to 10mg a day. It's a drug I definitely 'feel' when I'm not saturated. I initially became interested in it due to this -> "Since vitamin B12 and folate also affect mood-associated parameters, the stimulation of the transport of these vitamins into brain cells by lithium may be cited as yet another mechanism of the anti-depressive, mood-elevating and anti-aggressive actions of lithium at nutritional dosage levels.” (https://pubmed.ncbi.nlm.nih.gov/11838882/ https://pubmed.ncbi.nlm.nih.gov/11838882/) It does reach a point of diminishing returns for me and I become too sedated. I now take it irregularly.
