Is it safe to leave a throat lozenge in your mouth to keep your head clear and help you sleep?

As you probably know, it probably is not safe to have anything in your mouth if you might

fall asleep. If you use any type of cough drops or anything else like this to help you sleep

you should stay on your side so you won't be at risk of choking.

I used big oversized cough drops to help my daughter when she was still just a baby

but I kept her on one side and help onto one side of the cough drop while she had the other

side in her mouth and this is a whole different approach from what most mothers would take.
