Hi Buster, Hang in there! I know how you feel! I took myself off 10mg Lisinopril about 2 years ago because it was causing excruciating muscle aches and foggy headedness. Within 72 hours of coming off it the fog lifted and the pain in joints and muscles subsided dramatically. I now think it also contributed to my OCD; made my usually symptoms worse, possibly. Can't prove it of course. But I can tell you after getting off the Lisinopril my compulsive on-line shopping dropped off dramatically. Hah!! (Note: I don't recommend going cold turkey like I did, bp really jumped up, just find an alternative.) Currently I had to get back on something so trying the amlodipine but just started so can't say yet if that will work.
