[|Human|] I am 68 years old retired person and had by-pass heart surgery two years back. I am on dose of daily pills after my surgery and had been advised to minimize the water intake by 1.5 litres a day and drink only when thirsty. Since last 2 weeks I have following problems: 1) My mouth is getting dry. It is summer here so I am drinking small sips of water to quench my thirst but felling dry mouth very often. It leads me to drink more water and urinate without any relief from dry mouth. 2) I am feeling tired most of the time mostly after using stairs or short walk unlike earlier, so lie on bed to rest most part of the day. 3) Due to tiredness or I am sure the reason but I am feeling sleepy most of the time when lie on bed. 4) I am also feeling weakness now a days for no specific reason. Please note, I do not have problem of blood pressure and it is normal. I do not have diabetes with normal diet. Please advise if you diagnose anything unusual. I am remote part of small city and may need to travel distant place to see specialist in this summer, so your assistance would be very helpful for me. Y.P. Singh
