Hmmm......when the weather is hot & humid, I sweat, not 'perspire'! So often 'crave' salty foods. Have lately 're-discovered' original Pretzels, which I've not eaten for a few years'. Will also buy some good quality Feta Cheese.
Conversely, also happy to have some Dark Chocolate!
Pregnancy cravings were a totally different 'set of food'. Apple Pies, Ginger Ale, Stone Fruit, Roast Chicken & Custard Apples! Not all at the same time, though!
