Not me, but my neighbor was bit by a copperhead in our house when she lived in it (her husband built it). She said she just stayed in bed for a few days.

I know a few other people here who've been bitten by copperheads too. Some went to the hospital, others did the same as my neighbor, no one I know died but the hospital bills choked a few up pretty bad.

I don't know anyone here who's be bit by a cottonmouth or rattler. They're here, I've relocated two pygmy rattlers from our yard but never seen any others and water moccasins are in all the lakes and streams nearby.

If I got bit by a copperhead while out solo hiking I'd stay put if I were a long hard hike from contacting anyone, if not I'd probably try to get somewhere I could make contact, but I'd take it plenty easy along the way.
