well I am not certain if coffee would give high BP, or reduce it if you give it up, but for on O - the benefits are much more in other directions as well.. you have done your body a lot of good.. and done the most difficult.. gave up a bad thing..
For high BP I would to begin with follow the cardio book diet, and certainly see if you can afford to buy some of the supplements listed in the protocols -- look for them above-- then if you can get swami, but even more important, start walking .. for as long as you can every day.. or 20 min at least .. slow or fast is not so important but moving is.
I might add lemon water as well. helps to move the blood.
how are you experiencing you high BP? do you hear it or feel it? how high is it? are you taking meds?.. to heal BP you need to HEAL the WHOLE body.. this will take the rest of your life.. so give your self time do get there..
IF you are in trouble according to a doctor then walk some more.. and adhere to strict guidelines on foods for cardio and diabetes.. and stop the worry.. it can cause BP to spike.. no need, life will be what comes, so eat right and relax, even meditate or visualize a calm beach, internal health, and care free living, for as often as you can close your eyes for even a minute.. it will help..
patience becomes a virtue, so take your time and rest when you can.. but stay active,, all the best advice from others is here for you..
