Rob over at cockeyed.com has added an epilogue to his expose of herbalife. He did a real good job of showing how sleazy this company is. The letters he received from angry herbalife distributors are amazing. Especially the one that says:
You can tell you've never been a herbalife distribuotr, you are making uop the buggest load of crap and putting it on a web site. The normal person can live the life of their dreams through herbalife. I think you may be a little jealous because you cannot!
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
