I would die without ear plugs-- while traveling, and for catching some sleep in my VERY noisy residence hall:)

One more thing...When you have your earplugs in on the flight- be VERY aware that you will be prone to talking very loudly, without even realizing it! On my last flight, I put the plugs in, and fell asleep. About 2 hours later, a flight attendant tapped me on the shoulder and asked me to put on my seatbelt. Because, of the plugs, I could hardly hear her, and YELLED very loudly "What did you say?" I had no idea I had yelled so loudly, until my friend filled me in later Just a thought....
