I don’t know anything about the salt cravings other than it is a symptoms and can drive you crazy. I wanted to comment on something else you mentioned – I am currently on Prozac as well – my doctor’s reason for choosing this drug was because it was the most widely tested on females my age (22) so they know the most about its affects on me. Also, I don’t think the Prozac is aiding in sleep, as I very rarely sleep more than 3 hours a night.
