I would try taking l-theanine at night, it seems to work for me, and it might also improve sleep. By affecting neurotransmitters.
Low dose cialis is reported to slightly lower blood pressure, Gaba (amino acid) lowers my blood pressure for a few hours or longer. But I think l-theanine is behaving in a similar way to taking GABA but it is longer lasting. Nitric acid stacks are suppose to lower blood pressure, and cacao powder lowers blood pressure. magnesium lowers it, and dehydration can cause either high or low blood pressure. In people who are chronically dehydrated, when the body’s cells lack water, the brain sends a signal to the pituitary glad to secrete vasopressin, a chemical that causes constriction of the blood vessels. This causes blood pressure to increase which leads to hypertension.
Your E2 doesn't seem very high.
How high is your blood pressure and how much did it go up?
Attempts to lower it depends to some degree on how high it is and what causes it. Other factors that can raise the risk of having hypertension include obesity; diabetes; stress; insufficient intake of potassium, calcium, and magnesium; lack of physical activity; and chronic alcohol consumption.
As you can see, there is a lot that can go into affecting blood pressure.
