Welcome back! :)
Here's an idea...don't know if it will work... Was there a time when you were much closer to your goal weight (maybe when you were younger)? If so, how about tacking up a picture of yourself from around then in a prominent location? Maybe it will help you to psychologically readjust your goal, so you won't feel as subconsciously "satisfied" at 250.
As for what works for me (in terms of keeping myself from cheating), I've posted this before, but, in case you haven't seen it already and you might find it helpful, I'll repost here just the stuff about my own triggers and solutions, which are excerpts from the longer post about combating to cheating:
"For me, what seems to work best is to set a date in the future (for someone who's still in Induction, maybe four or six weeks down the road) when I'm going to allow myself a cheat meal (or maybe a cheat day) and know that I can have all those goodies I've been turning down when I get to that day. That way, I don't have the mental mindset of "I'm never going to be able to have that (whatever "that" is), but, rather, "I can have that in a few weeks." That helps keep me from feeling deprived. However, this strategy only works for folks who aren't true, hard-core carb/food addicts...for some people, having a little cheat leads to an immediate downward spiral into full-fledged binging. It's like the difference between someone who likes to drink a little too much and a true alcoholic who can't just have "one drink." So you have to know yourself and what you think will work for you.

For me, the two strongest triggers are feeling sad and feeling tired of having to follow *any* food restrictions - when it just seems too complicated to have to figure out what I *can* eat and to look around and see all kinds of tasty things and feel tired of being restricted.
The most effective strategy I've found so far is to talk to myself, at length, about the situation until I get tired of thinking about it and the effort to cheat becomes greater than the effort to stay on plan. Also, asking myself whether the cheat would really be worth having to wait THREE DAYS to get back into ketosis often stops me from an unplanned cheat. Finally, if I know I have a planned cheat coming up, I try to focus on that and convince myself to just wait a few more days.
The interesting thing is that when these strategies are successful against the "sad" trigger, it often makes me feel less sad, because I feel like I'm more in control. That said, if I were sad from a really significant event, I'd probably take care of myself by letting myself eat whatever I wanted for a day or two and then get back on plan when the initial, intense sadness passes or goes down to a more manageable level.
That said, sometimes I just need to pig out until I'm grossed out and actually looking forward to getting back on plan. Then, when I do, it feels so *good* that I don't feel tempted to cheat again. Also, I make sure to have a cheat planned for every few weeks, so I know that anything I crave in the meantime I'll be able to have in a bit when I do my planned cheat (which helps keep me from feeling deprived in the meantime). However, this strategy does not work for everyone - taking occasional planned cheats only works if you know you'll have the discipline to get right back on plan afterwards."
Hope there's something useful in there....good luck with this go-round and be sure to keep us posted on how you're doing!
