Any advice for me?I'm going to be travelling in August for a 15 hour car trip there and 15 hours back home. I'm so nervous I will have to go the bathroom and there won't be a restroom anywhere for miles. And when I have an urge to go I need to go ASAP. It scares me and I hate this feeling of dread. I want to go have fun, not worry. Please help. I've used immodium before and it helps, I have just never had to go this long on a trip. And what about when we stop to eat along the way??? AHHH...I am already stressing! Any tips or advice would be appreciated.Thanks.
