I was recently prescribed rosuvastatin (my first time taking any statin), and I had some very intense brain fog. How would you describe the feeling of what you experienced? The best way I could describe it to my friends and family was that I felt like I lost a quarter of my IQ and slept only 5 hours every night(I was getting great sleep, it just felt that way).

It was such a strange feeling. It's a weird feeling to know you're brain just isn't working as it has always worked.
