a 12oz energy drink will kick off the tired you get from mids, but not the couchlock you get from an indica (well not as much anyway).

headache yeah grind your shit better pick them seeds out! if ur rolling, i heard too much of some types of paper can do that, or swallowing too much bluntwrap if somebody got it all wet and sloppy.

sometimes people confuse 'headache' with 'head rush' sometimes i get a rush of a high like off a big bong or some other extreme hit that is not unpleasant but i guess intense... duno how to explain it, but its got a lot to do with pressure, and i could see where it would lead some to 'headache.'
