Look　After Your Voice
Often speakers at a meeting experience dry mouths and ask for a glass of water．Youcan solve the problem by activating the saliva in your mouth．First gently bitethe edges of your tongue with your teeth．Or press your entire tongue to thebottom of your mouth and hold it there until the saliva flow．Or you canimagine that you are slicing a big juicy lemon and sucking the juice.
Before you begin your talk, be kind to your voice．Avoid milk or creamy drinks whichcoat your throat．Keep your throat wet by drinking a little sweetened warm teaor diluted fruit juice.
If you sense that you are losing your voice, stop talking completely．Save your voicefor your speech．You may feel foolish using paper to write notes, but the bestthing you can do is to rest your voice．If you need to see a doctor, perhapsyou can get some advice from a professional singer．In the meantime, do noteven talk in a low voice.
What about drinking alcohol to wet your throat? I advise you not to touch alcoholbefore speaking．The problem with alcohol is that one drink gives you a littleconfidence．The second drink gives you even more confidence．Finally you willfeel all-powerful and you will feel you can do everything, but in fact your brainand your mouth do not work together properly．Save the alcohol until after youfinish speaking.
Perhaps you want to accept the advice, but you may wonder if you can ever change the habitsof a life-time．Of course you can．Coethe, who lived before indoor skatingrinks or swimming pools, said, "We learn to skate in the summer and swimin the winter．" Take this message to heart and give yourself time todevelop your new habits．If you are willing to change, you will soon be able tosay that you will never forget these techniques because they became a part ofyour body.

B．to askfor a glass of water
