cough
"Ok I am x ems/fire/law enforcement person .I am medically retired from this profession. I drive a commercial vehicle for a living now. I am also a heart patient/diabetic type 2. I get to drive all over the US and Canada. I have read numerous statements that  it doesn't work or does work. No it may not work for all. I started Monday taking this. It has slowed my hacking down quite a bit. I have not had any side effects of any yet. I'm about to have triple bypass done. I have tried over counter I found only one bottle of med I could legally use that worked. This seems to work for me at this. I will comment at least twice more  . I will use it up to my surgery date and a comment to all to how good it was or bad. Everyone is different meds."
