Control hypertension symptoms and conditions

I am a 44 year old female and experienced many of the side effects as shared. I have taken Lisinopril (20MG) for 5 years. I have experienced headache, nausea, stomach pain and now blurred vision, which I thought was due to just getting older, but the onset was so sudden, within the last 3 months. I have also experienced leg cramps and dry scalp. I have family history (Mother) with heart issues (by-pass surgery), but there has to be a better non-drug alternative to control hypertension. I am going to research and share my results as soon as I find a solution. Thank you to everyone who has shared their experiences. I thought I was falling apart.
