Ah Laryngitis; it sucks big time >_>
Usually I use a air humidifier to help me breathe better.
Also, try not to talk at all, even thought you can't, trying to talk while in that state, or even whispering, puts more strain on your vocal cords than when you actually talk, so that worsens the situation (I remember using a notepad to convey messages lol)
Gargling with salt water (warm i.e) helps to get rid of the bacteria and it soothes the vocal cords, usually takes a few tries, but it helps. You can also make ginger tea or cut up a single garlic clove and make a tea out of it.
One remedy that helps me alot is a bit of honey and lemon juice, mix those two together and drink it, it really helps. (Sometimes I try lime and high wine [a very powerful alcoholic beverage in our country] and you do kinda black out for a second lol but it sometimes instantly gets rid of the problem.
Good Luck!
