Hello, I Have Had Flu Symptoms Over The Past 2

hello,
I have had flu symptoms over the past 2 months. low grade fever 3 separate times usually after lots of work, less sleep and alcoholic beverages. I have also had lots of mucus and general congestion and a very slight sore throat for the last 2 weeks. After I get a fever i do not have as much congestion and my mucus is clear although i am still congested. I have been around a few different sick people. Should I see a doc or just try and get rest?
