But because MDMA releases so much serotonin, your body also destroys more than usual.

These feelings generally lasts around 3-8 hours, as your brain cells naturally work to reuptake the serotonin and have it chemically destroyed.

When something really great happens in your life, say you fall in love, there is an increase in the release of serotonin from nerve cells, which ultimately stimulates your body and makes you feel happy.

These same cells are triggered to release enormous amounts of serotonin, along with other neurotransmitters like dopamine and norepinephrine, which trigger even more electrochemical firing in the brain.

In particular, the neurotransmitter called serotonin controls appetite, sleep, memory, learning and in this case, mood.

This means when your brain function is back in its' normal state, there is less serotonin available to bind to your receptors and make you feel good with normal events.

However, this treatment remains fairly controversial as studies on rats and monkeys have shown that even small amounts of MDMA can not only destroy the endings of brain cells involved in the release of serotonin but potentially cause permanent brain damage.
