If you take a Bonine it’s not hard to catch up if your not throwing up. If you are throwing up than yes it will be hard to catch back up since you will just be throwing up the bonine
I'm happy to know that is your experience (or a loved one of yours), but having raised a child that has had extremely bad motion sickness since she was very small, that is not her experience. We could not even drive an hour on a turnpike with no real curves without her tossing her cookies. It was awful. She has really struggled with motion sickness her entire life, she is a young adult now, and when she has accompanied me on flights and/or and especially cruises, we have to get all "Rambo" in advance to keep her from getting ill.
Once she gets more than a little nauseous with motion sickness, she finds it very difficult to catch up and get back to "normal", even when she has not yet thrown up. For her at least, it is much like with her migraines: if you don't address it the minute it starts, you are in for hours of misery. On the Hawaii sailing, crossing the Pacific she did well until the last 2 days coming back to the mainland, where the Pacific current is very pronounced and causes the ship to "roll" which is the WORST for motion sickness sufferers. She still got very ill, even with Meclizine/Bonine onboard since pre-cruise, homeopathic tabs for motion sickness, the wrist bands for acupressure, and the acupuncture "seeds".
As mentioned earlier, ever since her pediatric neurologist recommended Bonine for her when she was little, that has been her "go-to" and for the most part, when taken in advance and continued through the trip, works pretty well for her.
