It’s been 3 weeks now, and not a mild cold, either. I’m talking a box-of-tissues-a-day, keeping-the-house-awake-with-coughing-all-night type cold. I guess since I’m pregnant my immune system isn’t up to much... but this being sick all the time is becoming exhausting in itself and is starting to get me down. Is there anything I can do to give my immune system a boost and get rid of this cold at long last? I’ve tried to rest, eat well, get fresh air... now what?!
