I ran out of pholcodine linctus for the cough but found a teaspoon of honey soothed it a bit. Hot water bottle for the chills, didn't need paracetamol for the temperature as I didn't have one. Ibuprofen for painful glands in the neck which I had at the very beginning. I also drank lots of water.
Crawl under the duvet, let your other half cosset you ( make it sound worse than it is, as they do ) watch a few series/films and relax. You'll be fine in a day or two.
