I have had lengthy discussions with people about the necessity of the MAOI diet, and I am not convinced that oral hamalas don't require it.  SWIM has had a number of scary experiences when coming down from huasca and thinking it was safe to drink a cup of coffee, smoke mexican terragon (tagetes lucidas), drink a beer, or eat a sandwich.  The uncomfortable heart racing from a quarter cup of coffee is enough to convince SWIM. He was always extremely happy to be at the very tail end of his MAO inhibition and grateful to no end when MAO came back and dispelled the bothersome hypertensive reflexes or whatever was bothering him.

Sure, you might not actually die from not observing the MAOI diet, but you will certainly run the risk of being extremely uncomfortable...

Of course, we are all different.  Some people might not get such reactions I suppose.  Still, I would be wary to advise anyone to disregard the restrictions.
