To sensitize the body to dmt, I've heard that one can first saturate the body with tyramine/tyrosine by eating lots of beans and bacon - this way all the MAO enzymes you have, plus the new ones being made to digest the rich food, will be busy working already when you smoke dmt. You have not inhibited the MAO enzymes, they're just too busy to get at the inhaled dmt that is floating by. I would bet you could keep MAO enzymes 'busy' for 2- 3 hours this way. I've been drinking a syrian rue extract regularly, on its own, and I feel it wears off quick. This is because I plan to vapouroize some dmt after MAOIs take effect, but then 'change my mind' (ie: chicken out!). So, four times in a row now I abort launching, and so I've noted how rue-extract alone is a pleasant 'tonic' for the mood/mind. And as I go to bed, it gives great hypnogogic imagery while falling asleep. But it wears off quick, in 2 hours MAOI effect is being degraded quick.
