I had a sore throat for two days and then the last two days I've experienced bad excess salivation. It's so bad it keeps me up for hours at night and even makes me nauseated enough to vomit if I don't spit it all out. I'm having to carry a spit cup with me everywhere. This symptom began with my last cold 9 months ago and is a relatively new symptom associated with a common cold. I'm currently on a cough suppressant and an expectorant to control the urge to cough. I do not have a stuffy nose yet. Mucus is clear. How can I stop this crazy salivation??
