Excessive Saliva produced

I am currently at 15 weeks. My morning sickness started at my 6th week and is still on going (but it isn't as bad now). However, ever since the morning sickness started, I have been having a build up of saliva. It could be when I am sleeping or whenever (except when eating). To a point that I have to keep spitting. It makes it inconvenient to even have a decent conversation without being "interrupted" by the saliva build up. My sleep gets broken as i have to get up to spit. Has anyone experienced this before? Will it stop eventually? 😵‍💫
