Just wanted to make sure I'm right about this. This is okay to use when flying, after 48 hours to make sure there is no side affects? I'm not sick or anything, I just can't sit for very long, if you catch my drift because of a swollen epidid. I supposed to be taking my CFII check ride and I don't the FAA guy asking me why I can't sit to long and why am I popping pills. Thanks for your help.
