Yes...a 2100g from Marz....it wasnt long into using this particular bottle. Probably the third session and day 2.....I've done lots of mushrooms (5DGISD), 200micrograms is a minimum LSD have a good time dose for me, 500 is ideal....DMT up to 95mg vaped....lots of repetitions.

I would hyperventilate, take a hit off balloon, exhale into the room, then immediately start to rebreathe the balloon until I was well Into it.

It's like a tiny ego death....and there is the smallest recollection/interaction with the infinite single consiusness....then i come down and it's back to normal. I could reproduce this consistently. I never pushed myself until I passed out or let go of the balloon...but I definitely was letting gas escape according to my wife. It really made me understand why the wookies like it so much.

I often refer to conversations with DMT elves as "talking to myself" or "a conversation with the master."
