The "10 lbs left" blues!

To anyone who's almost at their goal or who's reached their goal, as you got closer to it, did you feel at all discouraged? I just don't feel as strong as I used to anymore. I'm not saying I'm going to go back to how I was before, not at all - no way am I putting ANY of the weight back on! I'd never let myself get to how I was again. But I seem to have lost the drive to do well. I would NEVER give in to temptation in the beginning, but now I'm finding myself giving in here and there. Nothing big, but an example would be - last night I went to Nando's with some friends. I planned to just have a fillet burger (345 cals) and some mashed potato (220 cals) which would have kept me in my calorie allowance with around 50 to spare. Needless to say, I didn't stick to it and had some garlic bread along with it which was around 300 cals. I suppose it's nothing like my old eating habits (I honestly think I used to eat 3,000 calories a day - I'd eat SO much chocolate, sweets, biscuits, and just bad processed food in general for every single meal/snack!) but I don't feel I'm working hard enough to lose the weight anymore. I'm still working out, I'm still eating healthily for the most part and I still do want to lose more, I just seem to have lost the drive i had in the beginning just seeing if anyone else out there has felt the same & if anyone else can relate!

To anyone wondering.. from the start to now.

Male, 18 yrs.

Start - 200 pounds, BMI = 27.9
Now - 159 pounds, BMI = 22.2

Obviously I'm well in the healthy range now but I'm still 14lbs ish off my goal weight of 145 lbs with a bmi of 20.2. I'm comfortable with the way I look now, for the most part. I've dropped from a 38 inch waist to a 32 inch waist & I've gone from a large mens shirt size to a small/medium (depending where i shop). But still, I do still have quite a belly & I'd like my thighs to be a tad slimmer I just don't know what to do.
