Karma, maybe you just need to give yourself a bit of a break. When I first started, I just focused on the fat and calories. Not the exercise. I only did the things that I would have been doing anyway. It wasn't until several months in that I added regular exercise and began to actually enjoy it. Perhaps if you pick one or two of those items, you could build up a history of success with them too.
As far as the 2PM thing goes, what happens to you then? Do you begin to binge because you're starving? What's going on? Some of the other posts address the hunger issue.
I'm not one of those who has tried every diet and failed. This is the first time I was "ready" to lose the weight. I didn't know if Alli would work, but I was willing to give it a shot. Because Alli gave me a boost in the weight loss, I felt successful and kept with it. Not all of us quit sabotaging ourselves completely. I look at it as slipping up sometimes. Then I get back on the program. Yes, I may feel disappointed in myself if I feel that I may have eroded a pound that I had lost, but you know what? I'll get there eventually. It may just take longer.
I wish you luck and hope you're ready to stick with it.
