Has anyone ever been to these levels? If so what was it like? I've been at about the 2nd after taking 600mg. To get to the 3rd and 4th you have to take well over 900mg allegedly. I heard at these levels it's a full blown hallucination and you're in a completely different world with eyes wide open. Please share your dxm experiences at the these levels I'm considering attempting 900mg some time soon.
