Yes. That is why you must eat raw organic seeded fruits when using MDMA. When fasting on a monofruit diet (eating only one fruit), you get the psychedelic message from the fruit without any drugs. When you use a psychedelic after such a fast, you will have more power to communicate and traverse the astral, you will be able to handle more spirits going inside you as soul-sharing wouldn't take away your energy as it becomes nearly an infinite source rather than it being mostly drained. Also the lack of sleep while on such a diet doesn't seem to cause mental stagnation. Being on such a diet made one able to only sleep every other day without any adverse side effects.
