Hyperemesis Gravidarum

Yesterday was the first day I went without nausea tablets... Felt great in the morn and then progressively throughout the day got worse. Threw up my whole dinner for 2 hours at night.

I'm 12 weeks todah, have a severe headache I'm guessing from dehydration. Trying to drink more water

Wanted to ask you all if anyone has had experience with hyperemesis gravidarum? When did you know you were in that 1%? I've read you have to had a weight loss as well. How often did you throw up? I'm throwing up 2-4 times a day, mostly midday actually and at night like after I'm able to eat more than a snack.
