Hi Cara
Blood pressure is also effected by sodium so don't forget to try and reduce it, it did wonders for my BP now I average between 1500 - 2300mg per day (usually the lower) and since I reduced it several months ago I don't even notice the difference anymore. Bananas, beets and spinach are also great for reducing BP so if you are into a morning smoothie try those. You can get a mix called The Brainiac that only needs some spinach added
I know what you mean about chocolate though I have developed a serious sweet tooth since I quit.
Good luck
