It’s my understanding that 10% or greater is considered dangerous. Is the amount of your secretions easing up any at all yet? It really is best that you are getting it out. If you start having bronchspasm/wheezing or difficulty breathing that would be a concerning.3%, used quite a bit. Yeah, it wasn't a strong move. It was about 2am Saturday morning, I had strep and a fever. Wasn't myself. I'm still coughing up about a shot glass worth every hour or so.
Don’t beat yourself up. Most of us have done things we regret trying to feel better. :)
