I am 68 YO male with High blood pressure and high cholesterol. For Cholesterol I am on 80mg of Pravastatin. By mistake I took it twice yesterday at 12 hr intervals. Today I am tired and when trying to hike as I do daily, I got extremely tired and weak . A few years ago when I started on a statin I had the same reaction but my doc was not concerned. I have not had much energy since I started the statin a few years ago, but today was the first time I really feel like I can link it to the statin.
