You must have had a better placement of the needle.
The one time I had an IV the nurse "missed" inserting it into my forearm, pinched a muscle or some such, and then had to fall back to attaching it to my wrist. I couldn't use my left hand the entire time it was attached and for a few days afterwards.
Also, doable aside, I'm guessing you'd agree it's not recommended.
It's doable, personal experience.
