+1 to upping your daily calorie intake. Start higher and transition down to a lower intake.
You also used the word "fail" in your first post. Check out the quote in my signature.
I find it useful to give myself planned days where I allow small splurges. If I know that on Saturday night I'm going out with friends and I'll allow myself wine and dessert, then I find that helps me stay on track throughout the rest of the week. Saturday comes around and I enjoy myself, track my treats and carry on with my OP eating the next day. The best thing about calorie counting is that there are no foods that are absolutely banned from consumption! Have your treat/splurge/off-plan food, make sure you record it and track it, and carry on. Don't let one meal or one rough day derail the whole plan and all your progress.
