Hypothetically, for a fictional character...Xanax bar crunched up, mixed into margarita. Make it with liquor, not a bullshit wine product or malt liquor you get in a can/premix. Xanax causes transient memory impairment on its own, exponential effect when mixed with alcohol- especially for a non-user. !!!Make sure it is a legit Xanax from pharmacy, not an Extended Release version-XR- and not some street shit that is a pressed pill mixed with Fent.!!! (That would end her) If you don't want to squeeze fresh limes and an orange, get a mix. Use a decent tequila and splurge on a decent orange liquor like Gran Marnier. It is 80 proof 40% a.b.v where triple sec orange liquor is 30 proof or 15% a.b.v. The drink will be delicious and not taste "funny" or "too strong." You can enjoy one without the Xanax. To make sure nothing is noticed...Get a little blender if they don't have one to use at the hotel. Get it at a thrift store like Goodwill, a new one can be as cheap as $10 at Walmart or DollarGeneral. If you make it a frozen drink with blender, you can double up on the alcohol while still being drinkable. A good thing about Xanax is that you can have some fun with her and she will be responsive for a while. She will be "herself" or like she is when tipsy, fun, talking, laughing, etc...but nothing will be going into memory. Effect is intensified with alcohol and stronger doses. She can be slutty, treated like a whore, and acting like a whore but will have no memory of what happened as soon as it gets into her system and works well before she nods off. When she starts nodding off...go all out. You, buddy, group of strangers, pack of wild dogs, whatever....Just to make your fictional movie/story realistic....not to do for real of course...but Google the side effects and caution info on Alprazolam to see I am 100% correct. I was prescribed this and found out or learned the hard way...
