anxiety
"I mostly used Xanax when I had an altercation (verbal) with my girlfriend. She would over-react, and as a result I would get so charged up that I couldn't switch back to normal. Taking Xanax eased my nerves so that I could "start new" with the conversation. Very powerful though and lasts a long time. I took doses of 0.25mg (I'm 115 lbs). If semi-anxious, doses made me very tired. I blacked-out for parts of a night when taking 1mg. Memories of stuff that happened, felt like memories of dreams. Also cancels out ADHD stimulant medications."
