Hopefully the meds will kick in and will help soon. You can also put her in the bathroom and run a hot shower and the steam should help or use a vaporizer. Hopefully she will be better by Wednesday. Hopefully you can get her to the vet tomorrow if she is not better, so they can get her on the right meds. I would still travel with her, as they usually just sleep in the car anyway, just keep an eye on her.
