i as well nearly only lived on hamburgers. and some bread i got down in the town.
i've never tasted as good burgers and fries in my life.
they actually tasted meat and potato. not just sugar greece and frying-oil as most bigger chains here tastes like.
i tried a new burger each day

all good^^
lived on hamburgers, white bread and ham, 2-3L of coce or fanta and 1-2L water / day. and still managed to drop around 3kg and needed to go to the store and make them refit my pants afterwards.
i would've needed a few more weeks there. hehehe.
