Wow, that sounds pretty crazy. I've only been doing it twice a week for 2-3 weeks, so I guess it's possible there could be a build-up on the way. I would say that my awareness of the present moment is increased but I'm sleeping OK and no problem with apetite.After a certain threshold was crossed during a trip, I had full-blown extended effects that were absolutely crazy. For that week, my awareness was forcefully pulled into the present moment (in an unpleasant way), I had electrical sensations shooting all around my body, my heart rate was consistently 140 bpm, and sleeping or eating were impossible tasks. And the feeling of anxiety and doom were palpable. It was very much like a bad trip that continued for 7 days. It was all super mystical, but especially while it was occurring, the negatives outweighed the positives.
Though life has got in the way a bit this past week so it's been a bit longer since my last session. I need to be in the right frame of mind. All being well, I'll try again tomorrow morning.
