Hi, I am a 50 year old female with a history of Eczema and Sinusitis but no other known allergy. I am 5 ft 10 inches and, of weight, appx 175 lbs. I clear my throat from draining mucus a lot when i wake up with the fan blowing on me which i cannot avoid. I often feel tickles at the back of my throat, in and out of season, which prompts me to cough a lot. This also happens when i eat something cold. is Claritin or Histatussin good for me and if not, what is? Thanks
