Lisinopril and felt ok

I had been taking lisinopril for a few years with no apparent effects but last summer began waking with extreme fatigue and slight nausea. I also developed spiking blood pressure but that was stopped by adding a beta blocker. I have vivid dreams and often wake feeling worn out from the dreams.The fatigue is severe and accompanied by depression and anxiety. I also wake feeling hot in face and torso and have intolerance for heat.My dose is 40 mg and has controlled my BP until recently when I have had a couple high readings, possibly due to anxiety. I also had a couple of remissions when I felt OK fro a coule weeks, but the symptoms recurred..

ive been on Lisinopril 20mg for about years. Apart from the cough have felt ok - until recently. Then I noticed about 1 hour after taking the tablet I became terribly dizzy and light headed. Very hot and my heart racing and palpating. Told Doc but she said to continue taking tablet. I stopped it a few days later and felt a little better. Told Doc what I'd done and she said she'd put me on a 24hr BP Monitor. This proved my BP was so very low she then put me on 10mg Lisinopril. Again (my idea) I stopped the 20mg for 3 days (I thought it would get out of my system) then for 3 days took the 10mg. Disaster! Thought I was going to pass out with heart racing again and again, very hot and frightened. Thought I was dying. Doc then decided to take me off the tablets altogether - that was 4 days ago. She put me on a Beta Blocker to lower my heart rate and now I'm slightly better. But still get very hot and bit woozy in the head. My BP is normal, but just wonder how long this drug stays in your body and when will I ever return to normal. Thanks for all your comments. Good Luck everyone.
