How can i get rid of a hoarse voice over night?

Sit up during sleep: Elevate your head to prevent worsening reflux if this is contributing to your hoarse voice. Voice rest is helpful, gargling with warm water, decongestants and antireflux medication (prevacid, prilosec, nexium, (esomeprazole) etc) will also help. Stay hydrated and avoid coughing which can strain the vocal cords. Use cough medication if necessary. See your doctor to rule out strep or contagious infections.
