Back in the day, the obvious move would be to use the good ole' "r u going 2 ask y im asking 4 ur advice" (obviously exaggerated). I'm not sure that it'll be realistic now that auto-complete, auto-correct and so on are the status quo. So far, I've just written every word out, but kept each sentence overly brief. E.g. "Thing happened. Not sure why. Text me back."

Is this the way to go these days? Do you guys have a better way? Or are old abbreviations still enough in use to apply?
