Latley been taking vit d per my doctor 2000iu. Ive noticed that in the last couple of days that if i dont eat after so long i get ravenous and crave salty foods and also have a hard time swallowing. I also get dry mouth in between meals. Ive had several blood sugar tests to check for diabetes but i always come back in range. I went to an endo and he said based on my test results and how i looked that i didnt have diabetes insipidus. Well anither thing with the dryness is that my hair and even facial hair is brittle and painful breaking off from time to time. I avioid shaving sometimes because it gets so painful. Inever used to feel like this a few years ago and im still in my twenties dammit! Has anyone else encountered this kind of thing before?
