I just got over a bad cold, and it's just now settled in my throat. My voice was starting to sound a bit raspy today, so I started drinking tea with honey, and gargled with hot salt water and vinegar solution. I'm also not talking to save what voice I have left (writing notes, etc.). I have an important speaking engagement tomorrow. Is there anything I can do to to get my voice back before morning? Any recommendations, advice (related to my laryngitis?)? Thanks!
