yes. will try again sometime but from everything i have read nebulizing the Glutathione directly into the lungs should give me more results. Time will tell. I don't think you are supposed to do both of them at the same time. Also NAC can have some side effects. I took it for 10 or so days in the past and became very fatigued (not from insomnia that time). Had to stop. But if it helps without side effects i am sure it is worth doing!
