OK, hers the deal, i would love to do some clen, but...

I have a bit of a high profile, well not really high profile but highly visible job where shaky hands and sweating(i already sweat too much) just isn't gonna fly. Is the sweating and shaking mandatory or can it be controled? Does clen preserve muscle or just really go after fat? Beleive me, ive considered it but im not surt the sides will mesh with my lifestyle.
