Lack of sleep gives me headaches. Sometimes (but not always), 3D movies do too. They're always more fatiguing than 2D movies, at the very least.

They don't know, because I don't tell them. Otherwise, they'd bend over backwards to accommodate me, which would make me more uncomfortable than the physical pain does.
I give you permission to tell your friends that you don't want to risk a headache to spend time with them.
You'd choose differently than I would, apparently. Having tried both approaches to dealing with the situation (with other groups of people), I've decided that I prefer this one. You can take your condescension and shove it up your ass; it serves no useful purpose here.
I'll do something I fear will be boring or go to restaurant I don't love for my friends. But I won't take a 3D headache or eat at a restaurant that has nothing but stuff I'm allergic to, because headaches suck. (Turns out both my clauses converge on that "because".)
