Clen and blurred vision

Has anybody experienced this side effect? I seem to have no focus a long ranges unlike I did about a week ago. Also cramps are bad, I pulled a hammy yesterday doing sprints, it was acutally pretty funny. I've never pulled a hammy and I hope I never do again.

If cramps then you need to up your water & potassium intake!
As far as blurry vision it could be possible.....if the side effects persist after a week or so then I'd discontinue!

As far as cramps clen in the summer has made me jump out of bed while streching in the middle of the night and drop to the floor screaming. To prevent this increase water intake and gatorade helps.

My eyes are funny w/ Clen - slow to focus
