I do worry about dosage when it's medicine. But if all these other small Pokemon can take it, I see no reason why we can't.

[Anasui sips at the drink and scowls. It's not bad. Just not his cup of tea... or booze, so it goes. So he goes back to the cup he had before and has more Nanab juice.]

More for me, I suppose.

Why don't you just ask what the unusual effects are? The actual Pokemon should know what it is.
