I would be a bit careful with tyramine and a maoi, such as caapi. Even though it is not common to have any reaction, it is probably possible. Especially, with things like aged cheese.
Another thing you might want to be careful with is drinking too much coffee, yerba mate and/or green tea close to a session. Have heard that it can potentiate the maoi manyfolds, perhaps 10-20+ times, possibly causing a hypotensive crisis.
Also, don't take caapi when you are on medication that increases the production of noradrenaline, such as Mianserin(Bolvidon, Norval, and Tolvon). Mianserin is a weak inhibitor of norepinephrine reuptake and strongly stimulates the release of norepinephrine.
When you combine this with an mao-a, such as caapi, it blocks the destruction of noradrenaline, causing a really bad noradrenaline spike.
Other
noradrenaline reuptake inhibitors are:
Strattera, Edronax, Vivalan, Ludiomil, Nortrilen, Wellbutrin.
My girlfriend had a nasty experience with this combo. Took tolvon to sleep on the night before ayahuasca. Then during ayahuasca, her heart started beating harder and harder. Blood pressure over 200/100 - 100 bpm at times. Convulsions, really bad chest pains, tingling all over the body, almost fainting.
So, be especially careful with medications you take, but also watch out for the foods that contains a lot of tyramine. But generally, you can eat most things. Besides, there seems to be some people that are more susceptible to tyramine than others.
