I don't blame you. That's why I didn't go back to bed this morning.

I don't know if this would help, but I take ear plugs with me in my purse for such occasions, since in addition to loud noise draining my energy super fast, it makes it even harder for me to understand what the people around me are saying. If you want me to, I could dig up links to the two kinds I use (one disposable silicone putty, the other non-disposable silicone-rubber inserts).
