I know how you feel. My problem is not getting out to exercise because I do that on a daily basis, and feel really good about it! I get up at 5 every morning. Unlike Neets, I get to sleep in.

I even go to the gym at lunch time 3 days a week in addition to going to the gym before work every day.
My problem is staying away from the goodies that are in our Services Department. One large tin of a variety of cookies and beside it a container of candies. All of them are the bite-size candies, so of course, one won't hurt!
I have been able to lose weight, then something hits, like the weekend, and I have lost all control and perseverance I had during the week. The worse part is when the fruits and veggies are scarce in my fridge, then it's difficult to find time to go to the grocery store again to get more fruits and veggies. I have to get myself in gear and keep it going.
I did lose 30 pounds with WW. Then, menopause struck a blow to my wonderful goal. I've finally found something that keeps the hot flashes/night sweats under control, so now I have to get myself under control with the picking of sweets at the office. I know I can do it. I just have to stop and think twice or maybe even three times before I put something in my mouth.
