Help with excess saliva!

I know it sounds gross and it’s tmi but let me start from the beginning. I’m 11 weeks and found out I was pregnant at 4 weeks, so pretty much immediately. Since then I’ve had severe morning sickness, well all day sickness. I can’t drink water, a sip of anything carbonated, juice, or dairy INSTANTLY comes up. The same goes for any electrolyte drink like gators, pedyalite and etc as well as ice and popsicles. Some days I can’t keep anything down. There’s no trigger of what sets of my salive but I have so much that I have to spit it out because if I swallow it I will throw up or get more nauseous. And it’s to the point that when this starts EVERYDAY I have to spit every minute and a half to 2 minutes for 6-8 hours until I go to sleep. Does anyone have any suggestions? I tried gum that didn’t work and neither does cold items.
