I accidentally sprayed some bath & body works mist into my mouth at night instead of my moisterizing mouth spray:( am i poisoned?

No harm, no worries: As you can imagine, such mistaken use is very common for all cosmetics, personal hygiene products, etc. In the US, it would not be legal to market them unless they were safe regardless of such mistakes. The same applies to soaps, deodorants, perfumes, etc -- if you can buy it in a store, probably it's safe in small amounts like this. Don't worry about it!
