Infrared saunas symptoms and conditions

I have taken this drug, Lisinopril, for only 3 days straight. On the third day, I began to have sweats and became very weak and exhausted. I felt as if I had a heavy weight upon my chest that prevented me from getting the oxygen, I felt I needed, but couldn't get through normal breath. I became faint and my vision was slightly blurred. I also felt my feet as being quite cold during the night, although, my partner said, that my body temperature felt normal. I'm not taking this medication as of today. I feel normal this morning, and want to continue to do so. I have previously been able to bring down my High Blood pressure by drinking fresh juices, doing a detox diet with the eating of fresh fruit and veggies, doing warm infrared saunas for a few days to bring my high blood pressure down naturally. Taking this medication was an experiment, and I will take the safer, more natural way to control my high blood pressure.
