getting texture on hair

Yeah, my asian hair has a really weird condition - after i shower, my hair gets pretty poofy and whatnot, but when i go to sleep, it sits down all flat like hat hair, and is more or less clumped the way hair is after you rigorously comb it. i have no clue why this happens - its like anti bed hair. Anyway, its pretty annoying 'cause i can't shower in the morning without looking like a mental hospital escapee, and if i shower at night it looks like i've been wearing a hat for a month in the morning. So the solution i need is to either use some kind of product or method that'll mess up my hair and keep it like neat but with texture, if you know what i mean - like controlled messiness. Something that i can use at night and have it last in the morning.
