You finally calm down after a while. There really is nothing that you can do tonight, it's late and the store that you got the spray from is closed. You can conceal it under a hoodie tomorrow morning and go to the store. There surely has to be a cure there, assuming that it doesn't simply wear off in the morning.
After finally getting calmed, you take off your clothes and go to sleep.
**
You wake up before the sun has risen, though the sky is getting lighter. You can tell because you're outside in the woods.
With a start, you sit up and look around. How did you get out here? You look over your body and find that you're missing the boxers and T-shirt you'd gone to bed with. Your feet are muddy and have small cuts all over from running barefoot. You can't be sure in the dim light, but you feel like your body hair is getting thicker, warding off the cool morning air. You stand up and try to take stock of things. You're still human, mostly. Feeling your face, you can feel that there is simply more muzzle than when you went to bed. Your ears, while not nearly as large as a deers, they aren't completely human, either. As the light slowly gets brighter, you can see that your finger and toe nails are getting darker.
You try to get your bearings, but have no idea where you are. You strain to hear any human sounds, like a road or campground but hear nothing. There is the sound of running water in the distance, which makes you realize that you're thirsty.
You stand there for a long time, trying to figure out what to do.
