As far as OTC remedies go one of the best things you can do is incorporate some natural diuretics into your diet to help reduce water retention. As well as things to help improve kidney health/function since they control fluid balance in the body. This includes things such as Vit b & c, lemon juice, and L-carnitine. If that doesn't work, bite the bullet and go to the Doc for a simple beta blocker, ACE inhibitor, or something along those lines. Not wanting to see the Doc isn't worth the detrimental effects of hypertension
