Yeah, go ahead and flush. It'll hasten the demise of the cold. I've got a bit of a cold myself right now. Got chilled to the bone the other day. Yeah, I know better. I blame it on being a man. Sometimes we just do stupid things.
Hot spicy stuff, and the Zapper. A Cold should last three days, that's it. First day - runny nose, drip, drip, drip. Second day - sneezin and wheezin, blowin and blowin. Third day - Feels like you gotta sneeze all the time, eyes water up, still blowin and blowin. Fourth day - gone. Got the sore nose though. Use Puffs Plus with the aloe vera, minimizes the nose soreness.
