Hi Doneiam. I agree with others -- speak to your doctor a bit more to get clearer information about these concerns. One thing you might ask about is hibiscus tea; not only have I discovered it is a wonderful drinking substitute, but I've also read it may benefit blood pressure. Mine has been up too high for a few years (especially on those doctor visits where I came in hungover . . . yeesh) but I'm hoping it will restore itself now.
