I have been on Lisinopril HCTZ 20-25 for two months. I was started on 10 mg prior to this, but my BP remained high. I have started a headache that will not go away, 16 days ago & I am exhausted. I want to sleep all the time. I have checked side effects to this med & these are mentioned, but not WHAT to do about it. Help! I am miserable. I don't see the MD until the 21st of Feb. Is it wise to continue feeling this way? Dawn
