Morning, I Put Piece Of Chewing Gum In My Mouth

Morning, I put piece of chewing gum in my mouth last night Just in case I cough and have a very dry mouth, hadn't chewed it and fell asleep, when I woke coughing I felt for gum in my mouth and wasn't there. It feels as if it is stuck at back of my throat this morning?
Not sure if I should eat anything to help?
