Hi Dave, I have been using oral glutathione since May of last year and i noticed right away a noticeable difference in my energy level the most. I also notice when i switched from the brand i started with ( jarrow) to another brand i started to feel more congested. I switched back to the jarrow brand and felt way less congested within a day. From what i have been reading from others that have used it, you need to stick to whoever has the best brand with the most purity. Theranaturals and Iherb.com ( who has the jarrow brand) are the best so far. You may want to read up on it before starting it just to feel comfortable about taking it, and i would recommend you tell your doctor you are taking it as well. Use it WITH your other medicines ,not instead of. Unless of coarse you are lucky enough to do so well that your doctor takes you off of other meds <img src="i/expressions/face-icon-small-wink.gif" border="0"> . I take what the back of the bottle recommends ( 3 per day) along with 500 mg. of vitamin C , each dose ( to help with the uptake). The only way to know if it will help you is to try it. I would not recommend inhaling it ,if you have hemoptysis problems . It can be very irritating to the lungs. I had a funny feeling when i put up the websight for the curcumin for you to look at yesterday, you might get interested about the glutathione, since it was a gsh board you were looking at. Good Luck, <img src="i/expressions/face-icon-small-smile.gif" border="0"><img src="i/expressions/face-icon-small-smile.gif" border="0">~ Diane 39 / cf / diabetes / b.cepacia
