I live in the US and just received the Yuliv hydroxocobalamin nasal spray I ordered from the UK (thanks detoxpeople!). There are no instructions in the box. How do I use it?
It has a little plastic colloar on the neck of the bottle that I assume I need to take off for use. Do I put it back on when I'm done? Or to transport the bottle, such as when I take it on a plane trip?
