Hot tea with honey (there are plenty of herbs that will help like chamomile). Slowly sucking on a spoonful of honey also helps with a sore throat. I also find it helps to move from the bed to the couch because I’ll get sick of the bed and the bedroom and being in the livingroom changes things up. Also hot showers and changing the pyjama. Just anything that makes me feel like I’m not marinating in my bed 24/7.
