i think stopping yourself from having 'accidents' is a lot like quotting smoking or getting rid of a bad drug habit, cos in the same way as these, you are addicted to it. i have been trying for the past 18 months to stop, without any joy. i think that a big part in stopping is wanting to, if theres a part of you doesnt want to stop, then you will find it veery difficult to. like the others said tho, if you can find the underlying cause and put that right, ,it would be a lot easier. there are many alternatives i have had suggested to me, drawing with a red pen, scribbling on paper, unching things (not walls or owt hard tho), snapping an elastic band around my wrist i wind helps, ,its harmless but seems to do the trick to a point anyway. anyhow hope this helps.
