Supply consumption is

MIN(size-1, 1)

That's why. Size 2 humans and those ever-hungry Hobb^Hurgs eat 1 supply, but shamblers (size 3) eat 2, and war lobsters, if they're size 5, eat 4. All assuming the lack of the need-not-eat flag.

BTW, if you can Wish but you lack the nature mages to forge, I -think- you can wish for "food" and get some supply items in a hurry. Haven't cast it to find out how much it actually gives you, 'tho. Also, if you -do- have nature mages... look for a nature/earth mage who can get you Summer Swords, as they do stack with wineskins.

Regarding unrest, it might be good to drop taxes ~10% for every 5 points of unrest or so, if you've already dealt with the cause of unrest -- including restoring your own dominion over it, as enemy dominion causes unrest. Some provinces are better off with a permanently < 100% tax rate, namely provinces with unrest-generating sites.

If you need to get rid of non-amphibious units in a hurry, consider Gatewaying them into a province where they can't survive.
