The more I embraced my inner introvert, the happier I was. I had more energy when I was at work and with loved ones when I had spent some time alone in the days previous. I also had significantly less resentment towards my husband when I told him what I needed rather than wishing he would just understand what being an introvert was like.
If you're tired of playing the on-the-wagon and off-the-wagon game with food then taking the time to craft your own nutrition philosophy will be an extremely worthwhile endeavour. I think you've got to get to the point of being at least a bit frustrated with food and diet in order to create something meaningful and worthwhile for yourself.
