I haven't posted for awhile because I moved to a house. The move was very hard for me, but we are in and now I am trying to clean, clean, clean! Anyway, yesterday, I tried my sample of "024" and YUCK! The smell was awful! I couldn't stand it, it was making me sick to the stomache. I had to eventually wash it off and today I have a very bad headache. I wouldn't recommend this to anyone with MCS. Even my husband couldn't stand it Just thought I would let you know my experience with it. I did feel good for about and hour, but after that, the pain return in my back with a vengeance!
