I take a 450mg dose of Lithium once a day. How long I need to be without taking the lithium to be able to use a 1g of mushrooms. Remembering that the amount of lithium I have in my blood is low (0.32). I know many people will recommend not to do this ''mix'', but I want to remember that I'm dropping my medications because I'm fine, I'll talk to my doctor about it Tuesday, just want to get ahead and know better about it.
