I pretty much agree with the above posts.

However, although body size can have something to do with how a certain dose will affect you, it is not absolute. I usually prescribe 5 mg tabs and tell people to start with half -- if they are not snoozing within 30 minute, take the other half. I have had football player-sized men get zonked on 2.5mg, and petite women who were barely touched by 10mg.

And I would definitely try it first on the ground. Good idea.

Good luck and pleasant dreams!
