What is the gold standard of SN protocols?

[knowledgeseeking]

I have seen many SN protocols and they all seem to be a little different and a lot of people have to substitute drugs.

Anti emetic - metoclopramide seems to be the best. I think I'm going to take that and Zofran.

Anti anxiety - Xanax seems to the favorite

Beta blocker - Propranolol seems to be the one I see most.

Any other drugs recommended or are there better combos? I'm figuring out my protocol now and have all the above mentioned medications and want to know I'm setting myself for the most peaceful situation possible.
