Try some Bonine for the motion sickness. I had many days on the water without it and had no problems. Then, one day...

Since then I just take a Bonine before I go out, just to be safe. Since then, I forgot it once and it was almost a tragedy, but fortunately had it on me and took it a little late.
If you have no bait tank, you can build a bait tube for about $25-30. Less if you have a friend who is a plumber. That's what I use.
