Diet is one of the most basic and very FIRST thing doctors should be looking at. I cant believe they diagnosed you before changing your diet and lifestyle. I continuously find myself shaking my head over the sheer incompetence of doctors in the US. You will likely notice another big improvement once you get your sleep routine sorted. Meditation may take time to work but once it does you will find even more improvement.

Im so glad you are having good success. Goes to show how much it can help someone who was extremely moody. My BP is completely different to yours, and I already have a good diet, but if I eat crap, my body complains very quickly. Listen to your body and feed it right, you will lead a healthier life.
