Riboflavin B2 100mg right before bedtime will take care of sinus drainage. It will work in about 20 minutes. If not,try up to 250mg. I had severe sinus drainage for years.I found it hard to sit through meetings,church etc, without coughing my head off. I would eat and have a reaction to food and start coughing uncontrollably. Sometimes medications worked, sometimes not. Sometimes I would double up on medication. Now I take NOTHING!
