You might want to be careful about
eating simple carbs, pred does give us urges to eat these & this is what the weight gain/round face is often about
-- but a short dose like you describe shouldn't be a puffy or weight issue anyway.
You may have trouble sleeping! It's okay to take something to help with sleep -- sleep is so very important to our healing process. There are lots of over-the-counter options, just check with the pharmacist, the dr, or a rug interaction checker like
www.drugstore.com/pharmacy/drugchecker/default.asp to make sure you are safe.
Hope you feel better soon,
