I don't think she swallowed any coco fiber I feed her in a plastic tub. Though she may have while drinking if she knocked some into her water bowl. I've always used coco fiber for snakes and haven't had an issue anything like this so far. My guess is that the humidity rise during her last shed may have helped incubate a bacteria of sorts since this first happened after her post shed feeding, and in the article I read 'Vomiting vs. Regurgitation in Snakes' says vomiting that happens days after a feeding could be bacterial and is usually an internal problem. I also noticed some sort of fly in her tank a couple weeks ago but I just killed it and passed it of as one of the many random bugs I find in my house this time of year. I'm not sure if that could have anything to do with it like introducing a parasite or something. Ahh I'm thinking too much into it right now though. Time for some guitar therapy to get my mind off it for a while. Thanks again everyone.
