Whatever medicine they have. Went to the regular doctor yesterday, it's already the 1st.
I only used it once, and it improved my breathing. I'll use it before bed, so hopefully I sleep better. It tastes funny though.
Says you can use it twice every 4 or 6 hours. But the guy said to use it once, wait thirty seconds, before doing it twice. He said most people don't need the second one.
