high blood pressure
"This drug is exceptional.  For those who give it 1 star because they felt weak or dizzy I bet they need to simply reduce the dose.  I only need 10mg/day to drop my bp from 155/90 to 120/70.  Don't just trust the docs and take 40 or 80mg because this is a new drug and they don't know how to dose it yet.  The trick is to keep lowering the dose until your bp begins to move up from the ideal.  Many people here probably only need 20mg/day or maybe just 10mg for it to work."
