Your symptoms suggest viral fever
as this kind of fever usually is associated with body pain
and generalized weakness. Your drinking habits may not have triggered the fever but can contribute to the shivering, body pain. I suggest a day off from work and rest as rest is the cure for viral fever. Pain killers will help you deal with the body pain.
Also if you are a person who is constantly working on the computer, staring at the screen , please get back to me as you might need a eye check up if the burning does not reduce.
Hope I have satisfied your query. Get well soon
