I was the same way for years! I got bounced around once in a private jet, and even since then, the slightest bit of turbulence has sent me into a complete panic! It is just now improving for me, 19 years later. I definitely take Xanax, sometimes even the night or two before the flight as well. It has been a Godsend. The best part is knowing that I won't actually panic, so that I don't have to panic about panicing! It has broken the whole cycle! Maybe your Dr can adjust your dose, or try a different med. Good luck!!
