Morning sickness

I can’t find answers online so wondered what you ladies say.

Is it normal to have a bad stint of morning sickness then for it to disappear for a day or so and then come back?

I’m 9 weeks today and have been terrible all of week 8 but today I’ve been feeling great and wondered whether it’s gonna come back or whether I’ve not had it so severe because I’ve been snacking every 2 hours? 🤯
