I lift weights run swim and and also do hard physical labor. )Sometimes my work is easy and I have no problems) but when I am climbing and cutting trees and digging ditches and doing my exercise program I get so sore for often more than a a week at a time that I stop working out. One thing I notice is if I take ephedrine I feel better after a hard weeks work and can work out an I do not feel as sore. Is this a placebo effect or is something to it. What do you think. Thanks
