Sudden anger is unpleasant and scary. Members and family alike feel helpless for a little while, amazed (and maybe fearful) at what is happening, at how easy anger rises.

It may take a while to get everything right, but everyone has to begin somewhere.
Remember your body and mind are going through many changes and it will take time for the adjustment. This is a positive change in lifestyle and being prepared for it is essential.
