For the love of salt

I normally don't eat too much salt.  I occasionally get salt cravings but nothing too intense.  All that changed over the past three months.  I LOVE salt these days!  I love salty foods and I love putting tons of salt on foods that don't have much salt on them.  I truly feel like I can't get enough of it. Scott had read somewhere that women crave salt when they are carrying boys so maybe this is a sign of something?
