I drink whisky with a high percent of alcohol (45%) to deepen my voice but today it just dried out my voice & my voice is stuck in a female range. What's the quickest way to moisturize my throat?
I drank a whole bottle 500mL of water & my voice is still creaky.
I think you should get off the expectation that your voice, a complex and intricate part of your body, is a viable target for that kind of sledgehammer quickfix in either direction.
Keeping hydrated is a good longterm strategy for keeping your voice in working order. But it's not like you can undo prolonged intentional damage at the drop of a hat in that manner.
This sounds like "smoking a lot for a deeper voice gave me lung cancer. Which mountain's air should I best breathe now to fix it? I tried Mt Fuji but it didn't help and I spent more than an hour there."
Maybe you should be seeing a physician rather than StackExchange?
