About a month ago I was put on Lisipril in place of the Verapamil I was taking. My pressure was at 148 over 93 for the longest time and my PCP didn't like it. Since I've been on the Lisinipril I've noticed a difference in my sleep habits as well and I do have a cough that wakes me up in the middle of the night and I wind up sleeping the rest of the night on the sofa so I don't wake my husband. My doc never told me of any side effects. I'm so glad I decided to check out this web site. I will be seeing my doc again soon for a BP Check and I will be telling him about these things.
