I am taking 3g's of taurine daily with potassium before bed every night. This is my third day of clen @ 120mcg and I wasn't having any problems till an hour ago. I was at the gym doing 100lb db's on bench and all of the sudden I felt a painful spasm in my foot. I was trying to finish my set but I had to stop and stand up really fast. It hurt bad, and even now it feels bad sometimes. It is like a sudden sprain or something, like a spasm. Any ideas?
