haha i did that too... it wasnt too bad but when i couldnt stop the spin, i guess my legs got stiff and i pulled just a couple hundred feet low....try to relax your legs and keep your eyes on your instructor when he lets go, if you start to slip into even a slight spin correct with a light shoulder dip,
i got advice to also push one hand kind of down and left(if in a RH spin) which brings your shoulder down....didnt really work for me but once you stop the spin, you'll never do it again, which is true
