Drinking too much water and it depends on what you call too much as 3 quarts a day is good for your body, is very rarely a cause of high blood pressure. Hypertension is usually caused for excess weight, high salt intake, stress or some problem in the with blood flow in the body. High blood pressure is the pressure exerted against the artery walls. Now if you are not in taking too much salt some drugs will hold salt in the body like Imuran and it will come out in your urine. If you're over weight well I think you know the problem. You should reduce your salt intake to no more than 1500 mg per day and use herbs and spices to add taste.

Now that being said there is the white coat syndrome and you have to lean to relax but there is also a side effect to this white coat syndrome in that doctors and nurses are lazy. They don't care if your blood pressure is high or not so this is what you need to do.

As a Myasthenia patient you never take you blood pressure when you are lying down or in a laid back position. There is a condition in which blood pressure will change depending if you are laying down.

So you walk into the doctor’s office do not have him/her take your blood pressure until you have sat for 10 mins, sit up straight. NO CLOTHING BETWEEN YOU AND THE BLOOD PRESSURE CUFF. Take the reading at least twice with about 2 - 3 mins in between and the blood pressure machine should not be pumped up any higher than 30 above your pressure. So if you have 160/80 then they should only pump it up to 190. If you are caused any pain your blood pressure will increase. When I am passing kidney stones I have seen my pressure up to 220/xx.
