I just commented about this on another post. I always have the rocking sensation after returning home. On the last cruise someone told me to continue to take Bonine after I returned home and it would help. I figured it was worth the try. I took the Bonine for an extra five days and the rocking sensation was much less than normal. Of course, I am not recommending Bonine for anyone. You should always consult your doctor before taking new meds.
