I am glad to hear that you are going to the vet tomorrow. Your snake is exhibiting the classic symptoms of a respiratory infection, which should be taken seriously as there are often fatalities associated with this. The snake being so young does not help any matters. I can give you a heads up and that this will require repeat visits to the vet for antibiotics and may get to be expensive. Although sometimes these things happen by themselves under ideal conditions you may want to consider changing your set up. I am not a big fan of care fresh, it is a possibility that it could become a respiratory irritant.
