How long will these statin flu/post-exertional symptoms last?

I was on 80mg of a statin for 10 months and got "sick" every couple of weeks. Would feel terrible for 3-7 days, then would feel normal and great. All blood work shows no problems. Doc theorized that the statin could be making me feel sick, especially as an active athlete. I am 3 months off the statin and I still feel sick about a 3rd of the time. Might be a response to physical activity. Any advice? Help? Wondering how long until it gets better or if there is something else at play.
