  • Adherence
    Always
  • Burden
    Not at all hard to take
Dosage: 120 mg Daily
Advice & Tips: the medication works for me at the lowest dose. It lowers my blood pressure, but not too low now. I am able to eat and manage my swallowing and making sure my food goes to my stomach. I can't talk while I eat because I need to pay attention whether or not my food is going down like it is supposed to do.
