It wasn’t red tide. my guts were rerouted about 12 years ago to remove a large tumor in my colon (benign). Since then I’ve had issues with scar tissue sometimes causing partial intestinal blockages. it’s especially exacerbated if I eat too many nuts too quickly. it wasn’t nausea at all, but sever cramping as they worked their way through my system. Luckily this wasn’t a more severe blockage like I had about a year ago that put me in the hospital for a couple days. As uncomfortable as It was, I knew I was ok as long as liquids stayed down. if I start vomiting , its time to go to the ER.I'm wondering about a connection with stomach upset and red tide. My skipper was really ill on the first night and we had to pull into shore for a rest after which he was okay. He attributed it to an unaccustomed energy drink along with fatigue but I was never so sure. Another crew had food poisoning; one of the them had to drop out after treatment at a local hospital.
My wife took the sick fellow at CP1 to the hospital. It’s unclear what his issue was. It is notable that both crew on that boat had some issues. The skipper was much less affected and was able to continue after some rest. Was it red tide or what they had for supper the night before? no one knows.
