Okay ladies! I need help!

Malarie • 26 years old, Married, Mother of a 7 yr old girl & newborn boy!
I was diagnosed with HG (Hyperemesis Gravidarum) in the beginning of my pregnancy. It was the worst thing ever, I couldn't keep anything down, not even water! I lost weight and everything. Although it has gotten better, I still throw up now & then and I'm nauseous about everyday. Since having HG I developed an odd symptom that just doesn't go away and it makes me feel nauseous and is embarrassing. I seem to be producing a lot more saliva & mucus than normal. I'm constantly spitting and I always feel a clump of mucus in the back of my throat which makes me want to throw up! I'm desperate for this to go away or to find something that'll he rid of it! Please if any of you have experienced this or know someone who has I would love some insight & advice as to how to get rid of it!
