Cravings

I need help. My weight is 10st 8lbs now and I have started to develop cravings for different things that I have never liked or eaten before. For example salt. I haven't used salt in 20 plus years but I really have a yearning for it on everything. Another is coffee. I've never drank coffee in my life, I'm a tea drinker, but I keep wanting cold coffee and finally I've decided that I love Baileys Irish Cream. My first glass was last week and now thats all I want to drink all the time. I realise that this must sound insane but I promise it's true. Has this happened to anyone else and will it pass? Oh btw I'm not pregnant.....I'm way too old!!!
