Yeah, no. I didn't even know there _were_ side effects until I started to get serious "mental fog", memory loss, and morning muscle stiffness so bad it was difficult to descend down the stairs. I think it's harmful to suggest that it's "in the head", because these things are sometimes real, and they can often be resolved partially or fully by taking a different statin (e.g. rosuvastatin instead of atorvastatin). At best, you can ethically suggest they are _sometimes_ in the head.
