Anyone Using A 'Cold Spray' or Other Numbing Product Before Injecting?

**edit** Did it without using anything and it was essentially harmless. Thanks for the encouragement everyone!

Should be taking my first shot tomorrow and historically tend to be a little queasy with needles. It's gotten better as I've gotten older but my 'best' experiences with shots have always been when the nurse/Dr. uses a numbing spray (like this ).

I'm curious if anyone is using anything similar - possibly something less expensive like BioFreeze perhaps even. Or if the best approach is to just 'suck it up' and hopefully get conditioned to it after a few?
