USB-C ports are especially prone to dust/lint buildup that can prevent the plugs from seating properly in the ports. Worth trying to scrape them out if they stop working right. I like to use a staple that I’ve unbent, but it has been pointed out this probably isn’t the safest tool. Just avoid the contacts and only scrape the bottom and sides of the port. It’s amazing how much crap comes out if you’ve been using the device for a while.
Yeah, if DayQuil doesn’t work for you and NyQuil does, then it’s the antihistamine.
Use Sudafed or it’s generic during the day, that shit’s amazing.
