I have been taking Lisinopril for about 2 months now, I haven't experienced any of the side-effects until recently I started waking up with numbness on my left upper leg. Overall I get weird sensations, mild numbness & tingling on my arms, fingers and feet. Thanks to this site, I realized my overall changing sleep patterns and numbness can be attributed to this medication. I will call my doctor to see if I can stop taking it. On a side note, my BP is definitely lower. I am 29/male.
