@NoobInLife,
Even though you didn't have immediate transportation, you might have been able to call to make an appointment for the next morning, and also get emergency advice over the phone.
My veterinarian has an answering service, and if I have an emergency they will forward my call to the veterinarian no matter what time it is.
Even though everything looks normal now, I think an appointment with your veterinarian would be advisable. Maybe not an emergency appointment if everything looks good at the moment, but perhaps the first available non-emergency appointment.
If you don't know what caused last night's episode, then it is possible that this is only the beginning.
