The regime I recommend to everyone since it has worked for me for years (whenever I do get sick enough to 'take stuff')...
Standard personal care applies. Hot showers are nice for getting clean and steaming out the lungs. Plenty of water, simple food to that's easy to digest.
Rest in bed or bundled up and watching TV or something if not sleepy.
To promote better breathing and deal with drippy ickies...
:
Go to your pharmacy, ask them how you get the REAL cold medicine that you've heard you need to show ID for.

There are two drugs worth considering:
:
Night time (an hour or so before you want to pass out from exhaustion):
What used to be maximum strength over the counter Sudafed http://en.wikipedia.org/wiki/pseudoephedrine
Sudafed has stimulant properties, they're an unwanted side effect but if you're REALLY sick you should be able to lay in bed for a bit breathing well and slip off to sleep; I suggest it before bed ONLY, since it tells the body to stop making mucus which allows for a good night's sleep without filling the lungs back up.
:
Day Time (take with your first meal (literal break-fast(ing))):
Under many brand names (often Mucinex) https://en.wikipedia.org/wiki/Guaifenesin promotes coughing up the stuff that is clinging to the lungs. Be ready to deposit the results somewhere sanitary.
