Amlodipine
"After a 24 hour blood pressure test, it turns out I have mild hypertension. Was afraid to take but started taking 2.5mg before bed. I can't get over how amazing I feel now! I had no idea a small rise in blood pressure can make a person feel so bad. I practically leap out of bed in the morning. I have so much energy now.  I did have some swelling in my ankles before but it is completely gone! I read this was good for migraines. I don't get them that often and hope this medicine prevents them too."
