Tolerance to hallucinogens grows exponentially. If one take a blotter of LSD, wait 24h, then take another blotter, it will feel like [¼,½] of the original dose. If one wait another 24h and take another dose it will feel like [⅛,¼] and so on. With LSD one must wait a few day between doses to feel the full effects.

With psilocybin, the period of abstinence required to feel the full effect is measured in weeks.

I have no personal experience with Ayahuasca, but administered daily it is probably not too different from medical treatment with Isocarboxazid as the psychedelic component should dissapear and the MAO inhibition should persist.
