I recommend for people with colds:

• Vitamin D supplement, you likely won't be getting enough sunlight while bedridden.
• Even without appetite, force yourself to eat some fruits and veggies.
• Gargle and spit a mug of water, honey, and a lot of salt. It tastes bad but will heal throat and tonsil congestion and infection due to the antinflammatory and antiseptic effects of the salt.
• Keep your limbs warm and your head cool. Fevers over 100.4 are bad enough to seek help and fevers over 103 can be fatal, but you should avoid multiple showers a day (even though it soothes the nerve pain) as your body needs to maintain the temperature to fight off the infection.
• Even while sick, do your best to keep up on laundry. Change out your sheets and blankets whenever possible.
