getting off of Diclegis

Diclegis has been a miracle for me this pregnancy. I had awful morning sickness and vomiting week 6-12. I am now 14 weeks and feel like I'm "far enough along" that perhaps the morning sickness should start to subside (yes everyone is different) it makes me so tired and don't want to take something if I don't r ally need it. 
Anyway, I haven't taken it for two days and don't feel that great. Wondering if anyone did this and if it took them a while to get adjusted?
