I was put on Lisinopril 10 mg after my blood pressure was deemed to high.The first thing I noticed was the shortness of breath, like I had ran a mile instead of only walking a few steps. Nest was the dry cough that kept me up all night. Also sick to my stomach the whole week I was on it. My doctor took me off the drug three days ago, I still feel like crap.How long will this "poison" stay in my system? I have never felt so bad in my life and I leave tomorrow for vacation!! I do not even have the energy to pack.
