So Doctor told me to take only 20mg of
lisinopril every day. I did. Then, even more serious
headaches, dizziness, and feeling like fainting, and high blood pressure.
So Doctor then prescribed Atenolol 25mg per day. One week of trial. Even higher blood pressure around 170/110.
So Doctor then advised that I should take both Lisinopril 30mg in the morning, and Atenolol 25mg at night.
