I took/was prescribed Xanax about a decade ago for panic attacks I was dealing with. It's truely a miracle drug for anxiety - the same way Tylanol removes a headache, Xanax removes anxiety. There is nothing quite like it. I had 2mg 'footballs' and they were insanely potent, I would take a half dose (1mg) and usually that was enough to calm me down.
The effects are incredible and terrifying. Relaxed to a point I didn't think was possible, I felt like I could watch my family and friends all fall off a cliff without shedding a tear or anxious thought. If you've taken molly, I'd say it's the closest thing but it's not euphoric. Instead of being giddy, you're just chill beyond limits.
Then one night I forgot I had taken 2mg (it makes you forgetful) and when my roomate handed me a beer I said "sure". Chugged that, started the second before I realized my mistake. That's all I remember from that night. Apparently, I started laughing manically at something on the tv so hard I was falling off of our couch. I was talking in gibberish, or at least not making any sense, and kept asking the same questions over and over. Then I fell over and started literally crawling to my bedroom across the carpet, still mumbling gibberish, before getting to my bed and passing out for ~12 hours, straight. I've been 'black out drunk' before and always thought it was a tad exaggerated, as I would be 'blacked out' but still have some shards of the night, or pieces would come back to me. A decade later I can't remember a second of that night after I realized my mistake, this all comes from my roommates recount the following day.
it's not the most interesting or wild story, but the power of alcohol and Xanax cannot be understated imo. I've dabbled in way too much, and nothing has ever come close. I went completely sober a year later and haven't touched anything since. I knew a dude who wanted to buy it from me at the time. He's dead now, OD'd at 26.
