Welcome!
I am not a Doctor so my advice should be taken with a grain of salt. If the lithium you are taking is not prescribed, I would still recommend weening yourself off of it before taking this plunge, just to be safe. Corpus Callosum is a member here who happens to be a moderator and a medical doctor so you can send him a PM if you are really concerned. Besides that, it is wise to be free of anything that might interact with an MAOI because that could be the difference between a life changing experience to a life ending ( literal death, not ego death) experience.
Good luck and I wish you well
