I use a decongestant, like Benadryl Benylin, the active ingredient of which is Dextromethorphan, which at least keeps my sinuses from feeling they're packed with cotton.

If my coughing is really bad, I take codeine for it--in Canada I can buy Tylenol 1 pills of acetaminophen and codeine over the counter. Codeine is an antitussive.

(As you can see, I believe that the best medicine is medicine. I have physical disabilities and chronic pain which means for me, natural remedies often aren't effective enough. Not to diss natural remedies, but I kinda need the big guns.)

If I can't concentrate on things visually, I like to lie back on a heatpack and listen to an audiobook or podfic.
