According to Wikipedia, Hypotnatremia is essentially dehydration caused by drinking too much water - which causes your sodium levels to drop too low.
I am travelling for work at the moment. I spent last Saturday (9 days ago) walking around Dubai and drinking bottled water to combat the thirst. I think it was ozonoted water, so it is stripped of all the trace elements your body needs from water. In the first few days of this week I continued to drink similar types of bottled water (not mineral water) and went into a state of fever that I thought was malaria. The more water i drank the worse I felt. The moment I switched to mineral water I started to feel better.
I thought I turned the corner yesterday but am feeling a little rotten today again. I have been served water a few times in meetings today and I am not sure if that was bottled or mineral.
Is it possible that the CR200mg Tambocor has lowered my threshold/resistance against this 'dehydration'.
