Hi Nate, I have been using Glutathione since May 5, 2003. I do not inhale it, i only use it orally. It has helped me temendously in having more energy to do things like i used to. When i got cepacia , the one biggest problem i had was the constant feeling of being tired. I also notice when i do not take the glutathione i am more congested. I take it as it is recommended on the back of the bottle ( 1 to 3 capsules per day) with 500 mg. of vitamin C each dose to help with the uptake. I could give you links to sites if you want to read more about glutathione. Good luck<img src="i/expressions/face-icon-small-smile.gif" border="0"> ~ Diane 39 / cf / diabetes / b.cepacia
