If you're looking to impose a little zen, in tablet form, we refer you to Alex Prager:

'I’m big on supplements—Calcium and Magnesium are both great for stress; I usually only take these when I go to New York, I’m not kidding. [Laughs] They’re really good for calming yourself, your nerves and everything. I absolutely notice a difference when I take them…I can go to sleep really easily. It works. Another thing I take a lot is B1—it’s really good for hangovers, and if you travel a lot…it’s called the ‘morale vitamin’ because it really does boost your morale. Like, if you’re having bad dreams…or if you’re feeling really depressed because of the hangover. [Laughs]'
