Ditto...football tongue is a good way to describe it. My mouth always seems a bit drier then too, and I still have numbness to my tongue which makes things worse. lol.
Mine lasts anywhere from hours to a day or more. Affects my speech and makes me 'play' with my tongue more, between the speech and tongue thrusting it's as if my IQ has dropped 30 points. Purty! lol :P
