I started searching for alternative methods to medicate about 2004 when ALS had progressed to the point that it wasn't safe to play with fire and I bought a square Aromazap. I loved it! I bought 3 total. I am coming up to my 17th anniversary of my diagnosis, which is a long time! The average lifespan of ALS is 2-5 years. Although I am totally paralyzed, I have figured out a way to continue to medicate when I am alone. I still live at home by myself with the help of a couple caregivers. I will be ordering a WS before my anniversary on June 11. Just need to free up the funds! I love your products Ed and congratulations on your success.
