I also had a hard time with journaling my diet, however, when I did finally get down and do it I learned a lot about my self, and my perception of how much I consumed. My advice is that you be honest in your journaling, it's the only way you will find out how to get a grip on your eating habits. The surgery will not automatically cure your obesity, you will have to be committed to taking better care of yourself than you ever have in the past. To be successful and to stay healthy you will need to know how to eat the best nutritious foods, take the vitamin supplements you will need, maintain your hydration with proper liquid intake, and avoid some of the problems that can occur when you don't do those things. Changing nutritionists won't solve your problem. Write it down, it will be an enlightening experience.
Educate yourself, take responsibility for your own body. Best of Luck to you. Honestly, I wish you the very best. Linda P.
