Yea I know that is what Erowid recomends. Im not sure why, it really is high. maybe they just used whole or crumbled mimosa not powder.

Thats really strange but again perhaps fortunate that you all had a dud. Your brewing seems very good. I know for me 50g caapi really doesnt get things rolling but I woulod feel something especially with that much dmt. I prefer 100-130g but also I enjoy a heavy harmala experince. So perhaps either your vine is on the weaker side, and or you all need more than 50g for solid MAO inhibation.

My thoughts, back yuour mimosa down to a reasonable amount. 3-5g but keep in mind 5g is strong for some people and increase your vine. Id bump it up since you already know the vine isnt a hot one maybe try 75g caapi and have more of each on standby. no sense in wasting a whole another night. Read about how and when to re dose maybe.

Also dont worry about a light boil. We made and drank huge pots of aya out here over open flame and it was raging boiling. Still some of the strongest ayahausca I have ever drank. I doubt lightly boiling hurts anything.

as far as fasting, I wouldnt worry too much about what you ate the night before. all stomach contents should have been gone by the next night. However heavy slow digesting foods like pizza do make a big difference when eaten to near drink time. I like to eat lightly the day of. Lots of fast digesting foods like vegitables and fruits. I dont fast because I need energy when journeying. Fasting leaves me too weak to go really deep.

Keep us updated on your progress and if you cant find answers after you loooked ask away.
