Take Benadryl instead. It is nonaddictive.

I take it an hour before going to sleep unless I'm already feeling very sleepy. In that case I might take it if I wake up at 2am or whatever. I used to only take 2.5mg but 5 works so much better for me so now I take that much. It us been a game changer for my life.

I recommend taking it at bed time, after you arrive. Maybe the day after too.

When do you recommend taking it (before flight, when we get there, etc.) and how much? We are flying overnight and will arrive there around noon their time.
