Hyperemesis 7 + 5 any known cures ?

Becky
I'm 7 weeks and 5 days and ive had serve morning sickness for nearly 2 weeks now, I had to have fluids at the hospital where they also gave me buccastem which worked great until it started interacting with my other tablets I take daily and left me feeling horrid, does anyone know of anything other than ginger and the well known things that might help me? Id be really grateful! Also when did your pregnancy sickness stop? Or at least become manageable ? 
Thank you!
