I take Xanax when I fly. I have a prescription for a whopping 10 pills, and it usually lasts me three months. It does exactly what it's supposed to. "Banned, Period" is assuming your experience justifies taking everyone else's away, and those of us using them responsibly benefit quite a bit. 4x a day is also over recommended dosages, depending on strength - so that's more on the doctor than the drug.
