No, I don't have that. However, hot water (hot showers specifically) can increase my cognitive symptoms like crazy. Also I grew up near the beach, and the salt water seemed to cause my skin to itch somewhat, no idea if it was POIS-related or not because it happened before it. I never really liked the ocean anyway. I don't like being in salt water, plus I also had a slight fear of what I couldn't see under the water like jellyfish or even sharks, yikes. Stuff that could bite or irritate me pretty much.
