Stick with it and you'll be grand. When the time comes don't be afraid of eating. I was so worried after everyone saying 'oh those diets they all put it straight back on once they eat'. Such rubbish, if you re-feed properly and that's really important never skip the refers week. And then eat sensibly afterwards you'll be grand. I just took 3 months off lipotrim as I was travelling around the states and managed to maintain only putting on 2lbs even though I was eating out all the time.
It's really about re educating our minds to make good choices.
Good luck this week, your great loss will just spur u on.
