What should i do if i have this little dryness in my throat i have tried drinking something like vitamin water or something and it is still dry?

Try lemon juice: Try adding lemon / lime to water. If that doesn't work you need to have your glands that secrete liquid into the mouth checked and find out why the dryness. Most antihistamines make the mouth dry. If dryness is due to parotid gland blockage or inflammation, may respond to taking Clear.ease lozenges that contain papain and bromelain that reduces swelling/blockage. Need to rule out other causes.
