Cough
"I have use this 4 different times over a period of 7 years when I had such a bad cough that I couldn&#039;t sleep for days. As a tip start out slow just enough to get some rest. My prescription says 5 to 10ml I take under 5 ml twice a night once it wears off normally at 1am and it works great. I normally only need to take this two nights in a row and my cough is pretty much gone. So I avoid any dependency issues.  I don&#039;t advice taking it during the day unless your home all day and you don&#039;t need to leave. It&#039;ll make you very sleepy."
