Welcome to Gaia! ::

I think this is the first time I've posted in the forums here and I'm rather sad about that... I would've really benefited from some advice already. Well, now I hope to glean some guidance from you all.

I feel like I've fallen off the horse.
I've been struggling to lose weight for upwards to four or five years now. Firstly, I did weight watchers for about nine months and was pretty successful. I lost around 30 lbs or so.
Then I got tired of it and quit. I stopped eating healthy and exercising and I ended up gaining back about 15 lbs.
After my weight gain I tried losing it on my own with my boyfriend's help by trying to eat well and going to the gym about every day.
That didn't last and my results were sluggish.
I stopped caring again. Then I hit the wall, got fed up with myself, and joined weight watchers again. The second time around, my progress was pitiful. Bouncing between 13 and 15 lbs lost in a period of 6 to 8 months. I quit again.
Since then till now I've stopped caring. Yet again.
I've been eating all the wrong things and haven't really been exercising. I don't know what I weight right now, I don't even own a scale.
Basically, I feel like I've lost the power to lose weight. My struggle with food is exhausting and the food is winning.

I need advice on how to become motivated and grow some strong self control and discipline because I'm severely lacking those things.

My stats: 5'6" tall
Last I knew my weight was between 170 and 175lbs.
My goal: 145lbs
Just for kicks, my heaviest ever: 230lbs ish
My lowest: 163-165lbs

Well, I'm glad I'm not the only one that struggles!
But yes, I should really get a scale but I'm afraid of becoming obsessed.
Self control is my enemy and has been forever. I guess I just have to practice telling myself no.
By the way, I know about binging. I'm a terrible binger at times. I'm also a binger that post-binge becomes so guilty it puts me in a bad mood for hours. It's terrible and unhealthy. Ugh.
Well, I think I'm certainly going to be a frequenter of this guild now, which is what I should've done ages ago when I joined.

Not surprisingly, you're getting conflicting answers. Different methods work for different people - it might be a good idea to try out a few different methods to see what works.
Now for a biased opinion - I tend to quantify as many things as possible. Points counting, weighing myself every day, counting grams of fat, etc. provides a sense of relief in that I know for sure what I'm doing works. Also, there's a certain amount of safety in weighing oneself every day - usually the scale won't show a drastic change. For me, the scale is a healthy motivation. There have been days where cheating sounds extremely tempting, then I get on the scale and see a small loss, which brings my mind back to my goals.
The lack of motivation is understandable. At your highest weight, things are looking pretty bleak - you're thinking about where your body and health will end up if you continue doing what you're doing. If you're 60 pounds below your highest (and congrats for losing it!), it's easy to not make a big deal out of five pounds because your weight is still nowhere as bad as it once was. What I do is use a really unflattering picture at my highest weight to remind myself what will happen if I slack off for too long.
