Reddit reviews El Canto Del Tiempo/Ayahuasca Ikaros

Sounds loco to me to not have a sitter. But you asked for advice and not judgement, so first off get yourself some Icaros imo. They will help you anchor and chill out if things get rough. The songs are meant to heal, guide and protect. Download some, listen to them. In particular I really like this one and this one is also excellent (and from Shipibo tradition, so it's very different from first one linked)

To some of your Qs:

Dose: Personally, I would take the whole amount in one dose. For me if the first cup doesn't work, the second one rarely helps. You're also a big guy like me and I've always had the feeling like standard cup sizes are a bit too small, so a slightly bigger dose may be just right.

Dieta - refrain from weed for as long as possible before hand. 1 week should be more than enough. You want to have maximum mental and emotional clarity and balance for the experience. Following a Plant based diet for a few days leading up is a great idea. No need to fast day of, in fact you may want to have a bit of something just for the blood sugar, but it's up to you. Just keep it very simple, a bit of fruit and a couple eggs for breakfast works great for me, then fast until it's time to drink, generally once it's as dark outside as it's gonna get.

Noise and waking people up: I hate to break it to you, but doing this in a house full of sleeping people who you don't want to know ... GOOD LUCK. Prepare to puke louder and more intensely than you've perhaps ever imagined puking. Giant, earthquake inducing, waterfall roaring, inter-dimensional puking. Personally I think drinking Aya in this situation is a recipe for unwanted complications. Like, what if these sleeping people awake and start pounding on your door to check on you? How will they understand what you are going through and what you might need from them? Sounds like trouble to me. At any rate you should be prepared for that.
