I am 63 years retired male having good health. Every morning I walk about 8 km. On saturday and sunday instead of walking I play golf. In my golf course one full round requires about 10.5 km walking. I am always feeling thirsty and without minimum half a liter water my thirst does not go. In a day I consume about 8-10 liters of water, even at mid night while sleeping my throat get dry and I had to drink water at lease 2 times. I am not diabetic and have normal blood pressure (130/80). Please advice me how can I reduce drinking water ?
