Regarding the timing of when you take your medication, in the past many doctors did recommend taking blood pressure medication at night. That was based on the fact that heart attacks happen most often in the early morning. In theory, bringing blood pressure down during the night lowers the risk for a heart attack in the morning.
The reality does not match up with that theory for several reasons. First, blood pressure naturally tends to drop during the night in people who do not have high blood pressure, as well as in most people who do. That means there's typically not a critical need for medication to lower blood pressure during the overnight hours. Second, today's blood pressure medications last quite a while. In many cases, they only need to be taken once every 24 hours. When you take the medications during those 24 hours should not matter, as long as you take them at the same time every day.
