I saw someone else mention Aerobika. What is it? I guess I could look it up. I only use 3% saline solution right now. I just recently started using a nebulizer. It helps a lot, but I see that many/ most people use 7% solution. I might ask my doctor, but he did tell me that some people get sore throats from saline nebulizing. I wonder if that might be because of the stronger solution. Does that ever bother you in that way?
