My doctor prescribed Hydrocodone and that was the only thing that suppressed my cough, but it's a narcotic and can be addictive. I only take about 1/4 of a pill and it suppresses my cough for up to 8 hours without making me drowsy. I'm also having the air quality in my house and work checked for mold. I got a cold-air humidifier but that just seemed to make my cough worse so I may be purchasing an air purifier instead. My doctor thinks I have allergies because it's a dry cough and I don't feel sick. I also don't have asthma and I only cough when I'm moving around the house or work and I rarely cough when I'm asleep.

Ginger remedy relief for dry cough: Miracle. My dry cough became so severe I couldn't stand myself. I sliced a dozen very thin slices off a ginger root, placed them in a small 6 oz glass bowl and added orange juice. The orange juice softens the ginger slices and taste. I chewed one ginger piece at a time and sipped on the juice. After 8 slices and drinking the juice my coughing stopped. I keep a small bowl of ginger slices mixed with orange juice in the fridge and chew on a piece if I start to cough.
