You're a doc aren't you? I don't know what discipline, of course, but speaking of vegetarians, a friend of mine some years ago was advised to go on a diet of raw vegetables for a few days (or some time anyway). He told me that after a couple of so days he felt he was on a 'high'.

Would that be normal? Maybe something in the vegetables, eaten raw and without any other food to buffer them, causes that sensation ...?

lol apologies for doing the 'oh hello, your a doctor are you? - well I have this pain ......' :P

Greeker this isn't strictly OFF TOPIC, because I had been wondering if fasting may cause the same type of 'high' - I think it is known to be a way of increasing ones ability to meditate - sort of Guru style. Can't express this properly ...
