As the others said, singlepickle (love that name), it's common and it won't last long. Make sure you're getting enough rest, & try a walk in the fresh air.
This first couple of weeks is dificult, with all kinds of weird symptoms & feelings showing up. Listen to your body, be good to yourself, give yourself whatever you need. Congrats on 5 days, you're doing great!
