I did not get the begining of your post. But regurge is an issue that must be dealt with. How long have you had the snake? When was the last time it was fed? From my experience baytril has never caused a snake to regurge. They may not eat because they are being injected which is an unpleasent and stressful experience, and if they are on baytril they are already sick. I have only had one snake regurge on me. The snake regurged the first two meals I fed it, two weeks after the first meal was fed. What a mess. The rodents were still intact, and very smelly. I gave the snake metro right after the regurge and again the following day and then again 2 days later, also gave her panacur twice. I let the snake be for a week then began to feed it small meals. It started to eat again and I have never had an issue since. My guess on my snake is it was WC that had never been treated for internal parasites. Internal parasites can cause the regurge problems, and also the diarehea. Discuss it with your vet, if you could bring in a fecal sample that might be helpful.
