I get right-side headaches. I had one the other day. It went behind my eye and gave me bloodspots again. They suck.

Loud obnoxious people (especially when they are my peers), loud children (especially if they are being repetative), the smell of cigarettes, coffee and bacon (all make me nauseous), certain grammatical errors (et cetera is "etc" not "ect"... and the infamous "most bestest"!), other people insisting on talking to me when I'm not interested, ticking clocks (sometimes) and other noises like that... Yeah, this is a long list, better stop now...
