Hi. Well, the good news is that med worked so well for you so quickly! Bad that you have a side effect. I've not yet started any medication for my borderline bp. What I have read about the particular medication you are on is that you describe a common way people feel when first starting the medicine but that it is short lived and these type of side effects go away. My suggest is to maybe see if you can just stick it out a week or two to see if that is the case for you. I hope so since the med had such a dramatic effect! Let me know how it goes. I'm on my way to medication myself in the near future, I'm sure.
