So I recently got I-Doser, and tried it on one of my friends using the QuickHappy dose. It seemed to work, and she was smiling and laughing through most of it. Next we tried some other small ones, which all worked, and came to Black Sunshine. After five minutes, she threw the headphones off and said she was done, because she saw images that were making her uncomfortable and scared. By the way, I didn't tell her what tracks I was playing, just to make sure she got the experience without knowing what was coming, another validation process for me.
Once she was done, I threw on the headphones and played QuickHappy. I smiled a few times, but I think it was just the fact that she was watching me while I was laying down on my bed. Next I listened to Peyote, which had a huge effect on her, and she described seeing a "Small door and a train coming through it" while listening. Nothing happened for me. I listened to the whole track with no affect whatsoever. Next I listened to Black Sunshine, and I was sure something would happen; but it didn't. Nothing at all.
I'm a big dude, 6'1 and way over 200 pounds. Could my weight have something to do with it? If not, could you suggest ways of making the experience better for me?
