sea sickness can happen to anyone on any day depending on your personal circumstances. (except for Neo [Brett], as he points out to me...) i have seen folks "talk" themselves into it... i have even "talked" myself into it... the worst cases i have seen have always been on days with less than 2' waves on Erie. these folks just had something going on - be it other medications or some condition and the chop just put them over the edge.
some factors i have seen that will "enhance" your chances of sea sickness.
- stress - in stormy waves - get into calm and the "relief" then makes them sick...
- stress - excitement of going on the big lake
- dehydration - body chemistry is unbalanced - you need to sip water all day on the lake.
- too much alcohol night before - well, what do you expect if hung over?
- too much food or greasy food - i don't eat for hours before fishing just to be safe. lunch is at 9am when fishing anyway.
others have mentioned the "patch". what you are talking about is a prescription drug called scopolamine and the product is called Transderm Scop (
https://www.transdermscop.com/index.htm) I first used this back in the 80's when I navigated for an off road rally team. Motion sickness in a full face mask helmet (with intercoms - puking in the mic...) at 100+mph on mountain dirt roads (100ft drop to death to sides) when you are supposed to be giving the driver route directions is a serious issue! The "patch" just turned off the symptoms and i went from not eating for a 3-day event to eating in the car during non-race stages. If used properly, it will turn off the motion symptoms for most folks. You must put it on the night before going out fishing - the drug has to get into your system. The patches last for a few days, so putting it on 8-10 hours before you go fishing enhances the effectiveness of the "patch". I would wear one patch for the entire 3-day rally event - even stays on during shower if you don't scrub it directly. Note that it does require a Dr. to write the script - you can tell honestly what you want for - your insurance will cover some but typically is still a little pricey for copay (at least my meds plan).
Even though I run my own charter boat on Erie and fish some nasty stuff occasionally, when I book (I am paying) to ocean fish, we all "patch up" the night before... Why take the chance to have a bad experience.
