Another vote here for cold glasses of milk - can't get enough of the stuff! And potatoes - eating a lot more packet and hot chips than I would normally do, but the really strong one in first tri was mashed potato and cheese, yum!

Re sweet things, it had the opposite effect for me with ms. I would vomit fairly soon after having it (perhaps because it peaked and then dropped my bs too radically for me?) Anyway it didn't agree with me, and I still haven't really got my sweet tooth back.
