I'd like to just say "Excellent!" and leave it there - but will give reasons.
I liked the writing style. It is set out like a training manual which I liked. I have severe mood swings and this book helped me enormously in identifying and recognising the triggers to my mood swings were not unique or out-of-the ordinary. It enabled me to address the problem - and problem it is/was - with confidence. For example recently an incident occurred which would have left me devastated and low for weeks, but having 'Manage Your Mood' to hand and remembering the information I was able to Manage My Mood most satisfactorily.
