If you think you'll need more, just put them in a bottle with pills of the same shape/size (you can file the xannies a bit if you need) like no-doze/jet-alert or whatever, and fly with those. Just don't make them look hidden, put them with other meds/that sort of stuff. Or you can crush them to a fine dust, and impregnate them into something, like a chocolate, or whatever, as long as the thing itself looks stock/standard/non suspicious and isn't on the list of things they want to check specially or won't let you take.
