to Paulo:
Digestion is a highly complex system, with a lot of subprocesses involved. So, if you get a plenty of potassium in your food but somehow it doesn't get absorbed into your system, then there surely might be something wrong. I hope that eventually things get better!

I have a hunch that thyroid values being little high might be because your body reacts to the situation. Think about a primitive man: prolonged lack of sleep and insufficient nutrition most likely means a stressful situation, and the bodily system tries to fight that. So, I hope that your inner caveman finds back the balance of a peaceful situation =)
