I read the whole thread for the first time just now and I have a genuine smile on my face. This is why this forum is such a great place! A new owner posed a question that was answered by multiple people. The OP then took the advice of the people on the forum and - voila! - problem solved. Too cool.
I am glad that what you did worked! Don't worry about the animal going in head or butt first, as they end up in the same place and are digested just the same. Also, the reason that she was acting funny after eating the second one was likely due to her still wanting more! They will often take a second or third item if the first one/ones didn't fill them up. Example: My wife fed our 3 balls on Sunday. When one didn't eat another happily took that one's rat as well as well.
Best of luck with your new snake and I hope you learn a lot from the people on the site. There is definitely a wealth of experience here to draw from.
