You don't need to cough unless you have to. :-)
Remember when you got your first shot?
Do you recall hearing someone say "turn your head?"
You are thinking, "WHY?"
You are less likely to feel the shot if you do.
Did the nurse stand on a pillow to give you the shot?
Were they wearing lambskin driving gloves
that made the needle glide in smoother?
Did the entire doctors office stop what they were doing
so there was complete silence?
Your focus is simply diverted by your not knowing
when it's going to happen.
Use that thinking when you get a crave.
Turn Your Head.
Don't Get Involved!
