I guess by now you've read that reversible MAO-A inhibitors such as harmalas do not really pose a thread in term of interaction with food (though of course still be careful if you're taking medication, also careful about mixing stimulants and harmalas). 

What dosage are you considering taking for ayahuasca?

You can post your trip reports/etc here in this thread or also in first steps in hyperspace, wherever you feel its the right place im sure will be fine
