I don't want it to turn into full blown bronchitis cuz I'm able-bodied and the super cough-curing technique requires a wheelchair you get the point make me healthy real quick
Zinc,N NAC and vitamin C. Lots of fluids. Get someone to lightly thump your back with the heel of their hand if you can't bring up congestion. Use a humidifier. Rub a strong menthol/eucalyptus salve on chest and back and lay with back on heating pad. Get better soon!
Heating pad (I have a lidl brand one that stretches over the entire bed) and a hot shower after every sleep or nap. Salmiakki gummies are great for sore throat, but sadly unavailable at many places, and many people absolutely hate them. Vit C doesn't really save it after the sickness had set in, but take it anyway and don't take more than 2g per day.
