I have a 100.2 fever, sneezing, coughing, running nose, sleepiness and nausea. Is it a cold or the flu? I've had this for 2 days.

Not clear. But there are simple tests for influenza A and B. If you do have those there is a medicine which helps but only if taken within 72 hours of onset. Go see your doc immediately. If it's a cold, more likely from your description, the old standby is chicken soup (Jewish Penicillin). Good luck!
