in spite of all of the fearmongering about women being dosed with date rape drugs, most of the time, they're just really drunk
but some options are "roofies," brand name Rohypnol (flunitrazepam), which is a benzodiazepine, and like most benzodiazepines, it causes anterograde anmesia
another popular choice is γ-Hydroxybutyric acid (GHB), which was actually legal to purchase without a prescription up until the 1980s or 1990s
γ-butyrolactone (GBL) and 1,4-butanediol (1,4-B) are prodrugs that are converted in the body into GHB, so end up having the same effect
chloral hydrate is an old 19th century sedative that can work, and was the original drug that people referred to back in the day when talking about a Mickey Finn, i.e. being slipped a Mickey; the problem with chloral hydrate is that it has a fairly narrow therapeutic index, and the fatal dose isn't too much higher than the effective dose, so if you use it, you're risking turning your rape into a murder
personally, i think drugging a woman is underhanded, and i prefer to just overpower her honestly; if she struggles, it just adds to the excitement, plus if she's conscious, you can make a big show of taking a pic of her driver's license and telling her that now you know where she lives and you'll kill her and everyone she loves if she goes to the hospital or the cops
