Suggest Treatment For Fever And Weakness

I have had fever since yesterday morning. It goes after I have a paracetamol tab but comes back again and the temperature everytime is between 100°F to 102.5°F. And I don t feel chills during the fever. Its summer here and besides the chills I feel as I normally would on a moderately hot summer day. Additionally, I would want to tell you that I had university exams taking place which ended day before yesterday. Due to the exams, I couldn t get complete sleep, had to travel a lot, and had some outdoor works; so I was exhausted and exerted beyond my body s limits. I was also under inadequate and incomplete diet for 3 days due to shortage of time and a lot of things to do. Can you please tell me what should i do to get rid of the fever and the weakness? I have to commence a 16 hours flight journey day after tomorrow (India to LA) which cannot be cancelled or postponed.
