Diclegis, anyone?

Julie
So it's my first pregnancy and I was extremely nauseous almost my entire first trimester and my Dr prescribed me diclegis. It def helped take the edge off and I only threw up about once a day/every other day instead of being nauseated ALL day every day. Since I've hit week 14, I am starting to feel better-- nausea fading, energy returning, so am trying to wean myself off of the medicine but the 2 times I've tried to stop I have gotten really sick all over again. Any ladies out there taken and stopped Diclegis? Any weaning suggestions?
