I also know that you can feel depressed after taking MDMA as the body takes a long time to reproduce the serotonin used when you took the drug...  Doesn't it also release dopa-mine? 

 

Yes, but one should eat a lot of bananas after using MDMA as it restocks the user's seratonine. There are also pills that restock this neurotransmitter

This is true, although the depressed effect is usually only noticed when used frequently and/or at high dosages. I always pre-load with 5-HTP (a metabolic precursor to seratonin), Vitamin C, and Piracetam; and I usually experience an afterglow effect for 2-3 days where I have elevated mood and energy level.  It also releases dopamine as well.
