Common Cold

I've been wondering a lot this week.....

If the "common cold" is so common, then why isn't there a prescription or medicine to make you feel better? I am going on day 10 of this cold and I am "sick" of it. I think almost my whole paycheck has gone to walgreens this week trying to find some medicine to help this cold. I haven't really had an appetite this week, but the only things I have been wanting are soup and ice cream. ha Awesome diet.
