Vomiting returned at 11 weeks & it's worse than ever!

I thought I was getting over the nausea and vomiting, but alas, it's only gotten worse, happening more frequently than before. I never thought I'd reach a point where it's normal - I can vomit and tie my hair up at the same time, lol. Before, I wasn't able to control it, so got puke in my hair... Enough rambling. I'm 12w2d with twins; I have my 12 week NT scan today. Praying they're healthy and growing.
