I fly long-haul more than most people, albeit mostly in business. I started taking valium for flying 7 years ago for a fear of flying when I was flying mostly economy. I started with 2mg, which was completely ineffective for anything, and then went to 15mg.<p>At the higher I didn&#x27;t notice any effect, until the plane started bouncing, and then I realized I didn&#x27;t care, which was perfect. I didn&#x27;t notice any drowsiness at that level, which may have been due to adrenaline.<p>Over the course of 6 years, my regular dosage approached 50mg as I kept upping it whenever I started to get nervous flying. If taking it while I got on a plane, I didn&#x27;t feel drowsy. It became not always effective.<p>About a year ago I made a conscious effort to wean myself off it over the course of 12 weeks, by flying a return business long-haul flight every week, and taking a little less each time, practicing the principles in Dr Claire Weekes &quot;Freedom from Nervous Suffering&quot; (essentially breathing exercises, although it&#x27;s a little more nuanced), which is in fact a book for agoraphobics which someone had suggested to me. I got down to zero, but found under 10mg then turbulence still had fairly heavy emotional and physical effects on me.<p>Now I take 0-10mg when I fly. I don&#x27;t notice any effects, other than I am less sensitive to turbluence. However, I exclusively fly business class rather than economy, which I suspect helps a massive amount.<p>During this time I also tried Propanalol at some high doses. I found it ineffective for fear of flying, but very very effective for giving presentations. However it started to make me short of breath, so I ditched it.<p>In terms of intoxicating yourself for flying, I have found Ambien to be highly effective. However, it seems many many people have bad side-effects from it - sleep-walking, etc - so unless you&#x27;re totally certain you can handle it well, I don&#x27;t know that I would recommend it. These days I&#x27;ll settle for 10mg of valium and some alcohol.
