Xanax is definitely not anything to mess with. Take it from someone who is dependent on Xanax. I have countless experiences with all types of benzodiazepines identical to the one you have posted, though most of these experiences took place at a young age where I like you was inexperienced and did not realize what I was messing with. These types of drugs are wonderful for treating anxiety, but when taken in recreation nine times out of ten especially when combined with another depressant such as alcohol, blackout and embarassment is almost a guarantee.
Not only that but when abused for extended periods of time tolerance builds rapidly, and if you were to suddenly stop taking them abruptly you risk having a seizure and possibly dying. Take it from someone who is dependent on Xanax and stay away. If you have any fun at all you most likely will not remember, and behaviors like this will only lead you straight into a downward spiral. For me it has become a huge ball and chain. Can't go anywhere or do anything without taking a pill. If you still feel the need to use these drugs for fun even after having had this experience, which I do not recommend but would not judge because I have made similar choices which have lead me to where I am today, then I would suggest taking no more then one milligram at a time in order to take the edge off. Any more then that is asking for trouble.
