Rosuvastatin

Doc put me on 5mg Crestor EOD and it’s giving me bad fatigue and head fog. He indicated I could even try once a week and that’s better, but the 2-3 days following a dose I am still fatigued and head fogged. I am generally well. Lean, 38yo male, exercise most days, eat well but prolly a bit too much sat fat generally. It’s been 2wk. Does this generally get better? I need a good reduction in apob, so something weak like pravastatin prolly not an option. Pitavastatin possibly; thoughts on switching?
