Mineral water symptoms and conditions

I´m 55 years old, and been taking Diovan 80 gr for more than three years now. Never had any problem, and my blood pressure is really under control. But lately I´ve been experiencing dizziness.Decided to reduce the doses to half a pill per day, and felt better. Did several tests with a cardiologist, and all seems OK, except that my blood pressure was again a bit high, and he recommended me to continue with the 80 gr doses. The Doctor attributed the dizziness to low mineral water intake. So I am now drinking 2.5 ltr of mineral water a day, but besides going very often to the loo, the dizziness did not disappear. Is it possible the Diovan is the cause.

I started taking Topomax three weeks ago and have been feeling spacey, dopey and drowsy since. My sleep is interupted, my feet and legs are numb and tingely much of the time and I have a hrad time concentrating. My skin is very itchy, too. But, what disturbes me most are the postings about hair loss. My hair is thin and fine to begin with -- I can't stand to lose any hair. My doctor didn't warn me about this. Also, I've not lost any weight on the drug, although I did give up drinking sparkeling mineral water as the taste changed dramatically. I am about ready to ask to be taken off the drug, although I haven't had a single migraine since I started, and before I was getting 4 - 5 a week and they'd last 1 - 3 days (and some up to 8 days), so this is a big improvement.
