Amlodipine
"I was prescribed this medication and don't recommend it.  I had insomnia when I was on it, and 2 days so far after.  It gave me cramps, nerve pain, weakness/fatigue, lack of interest in doing anything.  Anxiety, spasms, and it feels like the veins in the left side of my head have swollen.  My left side of my throat and jaw stay mostly numb even 2 days off.  If you are seeking advice on high blood pressure just watch your sodium intake.  Most Doctors and Nurse practioners that I've had met just seem to be pushers for the pharmaceutical companies."
