There's never been a negative to giving it except I have a serious aversion to needles but the women on these buses are the best at finding the vein they want.
You were absolutely right. It was a larger diameter needle than I usually have during my monthly blood work and my phlebotomist was a pro. I did not feel it at all.
(sp? firefox spell check doesn't know how to spell phlebotomist so I hope I got it right.)
