@alleycatkate That was a few years ago, and I was concerned of course. Thanks for your response. I liked your post and thought it was very informative, so no apology is necessary. I also try to be careful on how I word things and always present information and to leave a choice to the patient. I do explain how something can benefit, but also how something can be overlooked or missed, or even have a negative or unintended consequence, and I leave the medical decisions to the medically trained professionals. No one knows everything, and even doctors miss things, so as patients, we need to be vigilant about our health and question things if something doesn't seem right, but some times with questions, there are no answers. I just think that by sharing information, we all learn. NAC certainly has a lot of good benefits and there is a lot of literature backing that up. Thanks again.
