Weaning off diceglis?

Ni

With my first two pregnancies I had morning sickness which stopped shortly after the first trimester and now that this is my third pregnancy I’ve been also having bad morning sickness and started to take diceglis for the last 5 weeks. I haven’t felt nauseous which I sometimes do even with it so I didn’t take it last night and have been throwing up all day. Is this something you have to wean yourself off of or is it still morning sickness? I’ll be 13 weeks on Monday
