I take 5mg of lisinopril in the morning. I usuallly skip breakfast & drink 4 to 5 cups of coffee in the morning.I find myself getting lightheaded/dizzy spells on & off until mid-day.. I wondering if my BP may be dropping to low in the morning after the pill takes affect. I check my BP at night prior to bed and it runs 122/79. I also have been working out ( jogging ) since I started the lisinopril. Thanks
