I'm about 2 weeks into the winny cycle, and have been getting back spazams. The back prolblem started before taking the winny so I dont think winny has anything to do with my back pains, unless my back has gotten worse with the winny. Because of these pains I dont think I will be able to work out for another 3-4 days. Should stay off the winny until I get back into training, or just continue taking it even though I won't be working out. Thanks for the help.
