(I am "the friend" LOL)
Thanks, Doc. I was advised to call my AME regarding these sorts of things, and so I did - as mentioned I have not taken any medications yet but my dentist office does offer this sort of thing for patients who are undergoing things like extractions or oral surgery. I was unsure as a new student pilot what to do or what was legal but this has all been resolved now. My flight tonight was cancelled and I may or may not fly this weekend, I'm attending an FAA WINGS credit seminar with the 99s.
PS - Not sure if I am supposed to introduce myself somewhere on this forum, but hello, I'm new here. I belong to another pilot forum and thought I'd branch out a bit - !!!
If the flight is Dual, I'd say go fly on the Valium (tell your CFI) and lean from that.
