[header] How to cure a cold without over the counter medicine [title] Stay hydrated. [step] It's important to drink water during a cold since it can liquefy sticky mucous in your airway, making it easier to expel and helping with decongestion. You should try to drink at least 8-10 glasses of water each day. 
[substeps] If drinking water bores you, you can add lemon to the water to make it more interesting. Not only does it improve the taste, but lemon contains lots of vitamin c which supports a stronger immune system.
