Hello, next Wednesday I am flying to St. Croix from Rochester, NY. First its an ERJ 170 from Rochester to Philly at 7AM, then Philly to San Juan Puerto Rico on a 757-200. From San Juan to St. Croix it is the dreaded (for me) AT7 prop plane. We are arriving in St Croix at 3:30. My question is, aside from thunderstorms, should we encounter anything other than light turbulence? I have flown many times but still have panic attacks even when encountering light turbulence. I have a valium prescription (I am not flying alone). I know you recommend against this(in the past I have taken xanax) but I feel it may keep me from making a scene. I am not afraid of crashing or anything like that, I just tend to feel sick and really out of sorts when the plane starts to bump around. Thank you!
