I've never had one, and I've never found them appealing. There's
too much
crap in them, honestly.
Though to be fair, part of that is probably because I'm not a huge fan of sweets in general, and wasn't even when I was a kid. I always preferred salty and spicy snacks more. Or even savory.
Probably the closest to a Blizzard I ever got was getting the Frosty from Wendy's a couple times as a kid:

But as an adult, if I'm ever in a mood for any sort of ice cream/milkshake/sundae/etc sort of deal, I'll usually just grab a chocolate milkshake from White Castle. Sure, drinking one might be like trying to suck concrete through a straw, but they're pretty damned good (and you can usually nurse one for hours as it slowly melts):
