To the OP; you probably don't have access to it, or hell if I know, maybe you do. All I know is that an excellent drug for your situation as long as you don't start abusing it hardcore after, and as this is a harm reduction site, no more than dosing 3x per week, and 3x per day. GHB (gamma-hydroxybutyrate) or Sodium Oxybate, which is a prescription in parts of Europe and in the UK. The Pure Pharmaceutical version of GHB is the top notch quality salt, Na.GHB Sodium Salt. (4-hydroxybutanoic acid - also another name for it.)
^ Now if you do have access to some GHB, I would use this very carefully for this occasion, because too much GHB can cause Nausea, Vomiting, Myclonic Jerks (Twitches), and passing out without being able to be awoken for at least 4-5 hours. the GHB induced sleep is a *4-6 hour TEMPORARY Coma type stage where the user/patient is unable to be awoken for at least the next 4-6 hours. (Also sometimes called the G-Hole.) when a person has consumed too much GHB and passes out.
Now.. enough of me babbling.. getting down to business again. The reason I also chose GHB is because it does have very strong Euphoric and Aphrodisiac (which can also result in 24/7 around the clock dosing and severe addiction issues, other than that, its no more addictive than any other drug out there, but does indeed have some nasty physical w/d but nowhere close to the withdrawals from benzos + opiates combined. Besides, the GHB withdrawal period is quite majorly intense only for the first 12-24 hours. After that, you are smooth sailing. So I don't find it to be as addictive as a lot of things.
Now, what I would do, if you do want to get a hooker, by all means go ahead. What I would suggest doing is, well most likely if do you have a connect for G in your area, most likely it will be in liquid form and be the Na.GHB but in liquid form. If you do manage to find powdered GHB, to live in an area where it is readily available like it used to be back 15+ years ago. I would go with dosing approximately
2.5g-3g approximately 30-40 minutes before she gets there, or you go there. Dosing the powder is much easier, safer, cleaner, and slightly more Euphoric I find compared to a lot of Street GHB, or GBL.
Anyways, I'm tired.. and I probably fucked up writing quite a bit of this, and missing things I forgot to mention. *snip*
Anyways, I'm going to go smoke some Triple AAA Westside Canadian super sticky dank weed right now, and then eventually pass out.
Cheers :D
