Thanks. This makes a good deal of sense. Do you have a medical background by chance? My wife also, on a lose dose has reported the same phenomenom.
The doc wanted me to take Lipitor too, and I flat out refused after witnessing what it did to my dad, and reading some of things things I've read. Such as: Lipitor® Thief of Memory by: Duane Graveline M.D., the former astronaut I was refering to.
