I im writing this review because yesterday i took this dose and it was INTENSE!! It was actually the first time i really felt the effects after using i-doser. I listened to it while i was listening to some music, I don't if the music helped, or if the effect would be even stronger without the music, but the music helped me staying still for 35 minutes After some time listening to the dose, i started to feel kinda cold and hot at the same time, and my foot felt like it was burning and being poked with needles, but it didn't hurt at all! Some minutes before the dose ended, my eyelids start to open and close really fast, it was really weird. When the dose ended, I wasn't able to think straight, my thoughts were REALLY slow. Everything around my room looked like it was moving and changing shapes, and the light tones were changing too, I kept staring at my hand for a while, i started to look yellowish and crazy! I Can't explain very well what I felt and saw, but I really enjoyed it and recommend it to everyone who wants a crazy trip
