No ginger, bands, sweets, medication worked for me but it did get better around 17 weeks.
I would say if something gives you aversion, don't perceiver, stop doing/eating/smelling it etc. The most I could do was remove/avoid triggers but in fact that probably cut it by 1/4. I had to keep my hair tied in a bun and change my shampoo 4 times because the smell of hair made me vomit as did the smell of shampoo
but I got there with removing that trigger for instance.
