Yep, although not nearly as much as you, I've had enough blood draws and IVs over the years, that they don't bug me at all.
Actually, they've never bugged me, and I always watch them do it.
But, my veins can be hard to find for some, so I've had more than a few 3 strikes and you're out situations, where they had to bring in someone else to do it (the last during my latest ER visit for the fun I'm presently dealing with).
There was only one time I've ever had one of those procedures done where I never even felt the slightest bit of a poke. This lady was a master at drawing blood, and I told her so. Never felt the needle goin' in, or comin' out.
