Buspar = Full agonist of 5HT1A receptors.

"5-HT1A receptor activation has been shown to increase dopamine release in the medial prefrontal cortex, striatum, and hippocampus, and may be useful for improving the symptoms of schizophrenia and Parkinson's disease.[39] As mentioned above, some of the atypical antipsychotics are 5-HT1A receptor partial agonists, and this property has been shown to enhance their clinical efficacy.[39][40][41] Enhancement of dopamine release in these areas may also play a major role in the antidepressant and anxiolytic effects seen upon postsynaptic activation of the 5-HT1A receptor"

"5-HT1A receptor activation likely plays a significant role in the positive effects of serotonin releasing agents (SRAs) like MDMA (commonly known as ecstasy) as well."

Wait quietly for a few weeks while these receptors sensitize!
