how to get rid of excessive saliva!?!?

im 9wks pregnant and having excessive saliva, its so freaking annoying. it makes me drool in bed, gross ik. plus, there are some days where i dream of brushing my teeth, and spitting out those saliva in real life! its disgusting to the max. i chew gum, which helps me swallow it wout that nasty taste. but is there any way for me to get rid of it? or im gonna have to deal w it for a while?
