you have nothing to worry about.. the maoi diet thing is mostly a misunderstanding that westerners projected onto harmalas by assuming they were like pharmaceutical MAOI
Caapi or passionflower changa in a 1:1 herb to dmt ratio is relatively weak as far as changa goes. I still love it... but try making 10x caapi changa (see the wiki) if you want harmala heavy changa. Or throwing in some extracted rue harmalas into a changa blend your making
and mixing tobacco with harmalas is actually an incredibly common thing in the amazon, cubeananda. But yes, too much caffeine can be very uncomfortable
