Exhausted!

I haven't been sleeping too well lately. I think it's a mental thing having to do with my abhorrence to neighbors' sounds past 11:00 p.m. Thanks to the unwashed Dungeons and Dragons geek and his cackling bitch of a girlfriend who lived under us in Oakland, I'm now super-conditioned to become enraged at the slightest noise from neighboring apartments. This is not good.

Even when the folks are just making normal apartment noise (no thumping bass, thank god), it keeps me up because I'm mentally bracing myself for the next sound. I've tried to Zen out to no avail. Calgon take me away! I've half a mind to buy one of those white noise machines for the bedroom, but I don't want to spend that dough if the things don't work. Have any of you tried them? Help me Obi-Wan, you're my only hope....
