What Are He Side Effects Of Epidural On Taste Buds?

Hello, I am 2 weeks postpartum and have been having a problem with my taste buds (starting gradually) since day 2 or 3 postpartum. Anything that has sugar in it tastes really bad. Including toothpaste. Could this have something to do with the epidural I received during labor? Or just hormones or breast feeding? Thanks! (P.S. I m 27 years old, 5 5 180lbs).
