I have no idea what it is like to take that drug, but as a chemist it is quite a complex molecle.
Like prozac it is has fluorocarbon group to improve the solubility in the fat, which should make it go into the brain with greater ease. It has several groups in the molecule, and you would need to ask someone else to understand how the drug works.
See Pan and Wang, Acta Crystallogr.,Sect.E:Struct.Rep.Online, 2006, volume E62, o768-o770. You will have to pay for a copy of the paper but the IUCr web site will give out the cif file for free. for the cif file if anyone wants to look at the molecule. You willl need to get some software which can deal with a cif. PLATON or ORTEP are free and that will do it.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
