Do you guys know about Lions Mane Mushrooms? I take it every day.

I take lions mane mushroom and when I dont take it my brain craves it. NO SERIOUS I was off it for a while and then my brain was craving it like my stomach craves sugar! It apparently helps the brain. Do we have any mushroom expert’s on here! I want to know if this helps adhd. Or its just for general brain health.
