Last Night, I Was Thankful For Ear Plugs

I have these reusable earplugs designed for sleep, but I don't think they're designed that well, because if I have them in for too long, I get a mild pain in my ears. I usually can only wear them for four to six hours before waking up from my ears hurting, but sometimes I get a solid eight hours with them on. However, they do block out all low-level noise, so I can sleep well on the weekends, where there's lots of ambient noise from the bar hoppers and binge drinkers.
