Yeah, this ws definitely a pain. It seemed to get me whenever I would go someplace like Disneyland or a county fair and be walking around all day. Eventually I did some online research and found a product called Bodyglide. It's similar to a deoderant stick that you rub on your thighs before exercise. This stuff works wonders as well as I never have any issues whenever I use it. I still keep it around, but after having lost significant weight it's not much of an issue. So there is light at the end of the tunnel.
Thanks for sharing what works for you! Good luck on the jouney.
