I find that Bonine does a better job than Dramamine (1 that is, 2 has the same active ingredient) Dramimine makes me sleepy, I hate the stuff. I take one Bonine the night before and another the next morning. Works great for me and others who spend time on my boat. If you decide to try Bonine, I would suggest that you try some on a dry run before diving with it, just to see if it agrees with you.
The ladder ride is an adventure. If the seas are rough it can get exciting. The trick is to watch the boat and get the rhythm of the ladder. Get close to the ladder and when the ladder gets to it's lowest point plant both feet on the ladder, put some weight on them and hold on. Wait until the ladder gets to the top of it's travel and then start climbing. The objective is to climb only when the ladder is moving down, if it starts back up, just hold on and wait for the next downward cycle. What ever you do, DON'T remove your reg or mask until you are sure you are on the boat. There is always the chance of losing your grip on the ladder and falling back in. If you do lose your grip, it's better to get back in and away from the ladder and start over rather than trying to hang on when you have lost most of your grip.
