Meds are worse than Mother Nature

I'm having difficulty adjusting to my 2nd cholesterol medication that I've started taking within the past month. I've read that a side effect of zetia is muscle pain and my legs have been hurting the past week even with very little running. It took my body awhile to adjust to crestor so hopefully the same thing will happen with the zetia. I still plan on running at Minute Maid park in Houston this Saturday morning but not expecting anything special. A finish would be super.
