en.wikipedia.org/wiki/Gabapentin
“Additionally, Gabapentin has been prescribed to menopausal patients being treated with anti-androgenic compounds to reduce the incidence and intensity of the accompanying hot flashes[20]. Gabapentin may help deepen sleep, positively affecting deep, slow wave sleep, and reducing arousals during the night. [21] It could potentially be helpful for both sleep onset and sleep maintenance.[citation needed] Gabapentin is sometimes prescribed for RLS (Restless Legs Syndrome). Finally, it may be effective in treating akathisia —a side effect of antipsychotics that causes severe agitation and anxiety.[citation needed]”
