I have, and I'm with you - pickled garlic is so good. I also love that it's super easy to toss in a few (or more than a few) cloves of garlic alongside whatever else is going in the pickle jar, or to put them in some leftover brine after the original batch of pickles is finished.

Since you mentioned liking raw garlic for your sinuses when you have a cold, have you ever tried saving the brine from your pickled garlic for similar purposes? If not, I'd highly recommend it. I've found that sipping or gargling pickle brine works wonders when I need some relief from a sore throat, and if the vinegar is strong enough I've found it helps my sinuses as well.
