My brother says it gives him that "I don't give a darn about anything" feeling.
Myself, I don't feel a major change, but it seems to take the edge off. For example, I was freaking out about a dentist appointment (I had a previous experience that made me have an anxiety attack just thinking about going back), and about an hour after I took the pill, I didn't feel different but there was no anxiety. On the plane, seems to be the same thing. I've never noticed getting tired from it except once...I took it because we were supposed to be flying in very bad storms, but the pilot was able to take us over them. I ended up sleeping the whole flight...not sure if it was the medication or I was just tired that day because that is the only time I've ever taken it and been sleepy.
