Any info on difficulty urinating? We just upped M's dose from 200 mg a day to 400 mg a day yesterday and all of a sudden today he can't pee. Called his pediatrician and she said to give him a warm bath and if that doesn't help, to bring him to the ER. :::: Meltdown, here we come! He's dribbled here and there, but nothing much. He can't completely empty. He did go a *little* more than a dribble last time he tried (but still could not empty), but since I've had him drink a big glass of gatorade to stay hydrated (we spent quite a few hours in the sun this afternoon), so we'll see if he can pee that out in the next hour. If not, I guess we're headed to the ER in meltdown mode. I can't find anything about Seroquel causing difficulty urinating...yet I find it an odd coincidence.
