My Dr. told me today she will give me klonopin for a 4 hour flight, as it is my forst time flying and I am scared. I am alraedy on Ativan for anxiety, and she said I would need to quit taing it when I do the klonopin..which is only for the flight to and from. Are there any side effects i shouold worry about, and do you think it will work? Thank you!
