I took lithium for <redacted tendancy> it got to my kidneys never thought of more generally microdosing lithium. Interesting. Full dose yeah flat and sleepy. Not sure it was the reason for flat out brain rot. (Other factors were available maybe just getting older.) Full dose needs blood tests as overdose weirdly bad. From <relative> due to dehydration / holiday in the sun looked like almost drunk but not drinking slopy etc. Slightly clingy desparate for interaction with strangers. <Other factors could have been available>. Not informed of damage relative seemed to recover ok. <Nationalised medical system>.
