As far as the Annoying Traits go, if they really, fundamentally change the character or make them unplayable, change them. The point is to have fun, afterall. Or maybe talk to your Referee, and see if you can make an END or INT check to suppress the traits for a period of time, perhaps based on the effects roll, and then see what happens as they kick back in (say, no modifier for 1 minute per point on teh effect roll, then -1 for a period of time equal to double the effect roll after that, and the then normal mod after that). The Psychology skill could be used as a DM as well. (you understand why you are annoying, and can supporess it for awhile).
