Thanks. Am getting potassium levels checked (via Medichecks) and will talk to the doctor if that shows a deficiency.
I totally agree (I would never be patronising). If you are waking thirsty it sounds like you are peeing too much and this leads to thirst (although sometimes folk just are thirsty). High glucose levels would be the commonest explanation, but you have stated normal glucose levels. As you say, one would want to know that calcium not high, potassium not low and renal function OK so the GP blood tests would be really useful - also to know that your sodium level is OK ie not got too much water on board.. Magnesium I find a bit fiddly to work out cos folk with low magnesium often have low calcium levels so which is causing the symptoms of weakness etc (in practice, one jsut treats both).?
I presume not on any medication that makes one pee a lot - lithium is the commonest one after diuretics but few folk are on lithium.
It might be worth keeping a record of how much you drink and how much you pee over several 24 hour periods to discuss with your GP and considering further special tests re thirst and peeing a lot.
Hopefully, when these things are sorted, the cramps will go, but they are imperfectly understood - I have met many folk who have nasty cramps and no obvious cause is found.
best wishes
