I would advise that you be really careful about tying weight loss goals to specific time frames. In fact, although I still list 200 as my goal weight, I don't have any specific weight goals at all.
Goals are best made when they are tied to our direct actions, and we cannot directly achieve weight loss. We can only create the conditions under which weight loss is a logical outcome.
I am not losing weight. I am exercising and eating right, and weight loss is happening to me, as a secondary result of my actions.
Therefore, I try to make all of my goals relate to my eating and exercise, and let the weight take care of itself. There are just too many variables involved with weight to predict what is going to happen from day to day, week by week. Sometimes for days or weeks I don't lose weight at all, sometimes I lose more weight in 2 days then seems humanly possibly without the use of a machete. I can neither predict not control when these things will happen.
So, don't worry about missing a weight goal. Don't worry about why the weight is wobbling in place lately. Worry about those things you can control- check out your eating, double check your exercise. If those check out okay, your on the right track, no matter what your weight is doing. If they don't, then that might be where you want to shift your attention.
One thing, though: don't give up. Always remember that you control the goals, don't let them control you. Good luck!

And Congrats on 36 lbs lost! Don't take that success away from yourself!
