Hypermesis lingering

Kam • ♑
When I was 4 weeks I suffered severe morning sickness which landed me in the hospital for weeks I suffered for as long as two months without eating anything and having it stay down I'm now 15 weeks and some days and it's decreased alot but still have episodes of vomitting I think because I have an excess of saliva which I developed from pregnancy and isn't easing up I also have this weird taste In my mouth after drinking or eating which sometimes aggregates the nausea. I just wanna know how anyone else deals with this saliva issue and how to make it stop.
