Well I went to the health clinic on campus and they refused to give me a script. The guy came of as kind of stupid. I told him where I was going (Israel and Australia) and he asked me if I got all my shots. He told me he had no problem on his flight to Russia so I should be ok.
However I had to bite my lip not to laugh when he gave me this creative line of reasoning:
If there was a problem on the flight and it needed to be diverted or if there is an emergancy threa he wouldn't want me to be under the influance of sleeping aids.
