I always get the yawns. I hate the come up on mushrooms. About 20 mins in it starts with the yawns and I get really tired. There were times I thought I could fall asleep. After about 45 min I get a lot of anxiety. I start to second guess my decision on whether I should have taken them and the amount I took. That lasts for about 15min. After that, it starts hitting me and all anxiety goes out the window. I think the yawns and the pre-trip anxiety is part of the process. Almost like the "purge" when taking ayahuasca.
Once you take them enough, you recognize the patterns and phases of the experience. There is truly something amazing in these mushrooms. It's always a very "primal" or "primitive" experience for me. I can picture our ancestors thousands of years ago in a cave or around a roaring fire going on the same journey.
Little off topic, but does anyone else like eating towards the end?
