I'm another Weight Watchers devotee (3 years now) but at this point in time I don't really think of it as WW, but more of a sensible lifestyle change of eating less junk, eating more fruit, veggies, whole grains and lean meats and moving more. Sure, I still add up the points in my head at the end of the day and enter them in the journal buddy thread, but basically I'm eating sensibly and exercising more than when I was obese. I particularly like the WW idea of not having to buy special foods and not restricting certain food groups from your diet.
I don't go to as many meetings now because as new people join I find we're covering the same topics over and over again, but I do have my core WW friends and we get together regularly for a healthy breakfast and supportive chat. I threw away my own scale (I was enslaved to it) and rely only on the WW one, so there's times now when I only weigh myself once a month, but I can feel in my clothes if I've lost or gained and have decided I'm more than a number (I may think that way because I find it difficult to reach a certain number)

Following the WW plan, I lost 3-4lbs. a week for the first few weeks (because I was so big) and then it tapered down accordingly to the expected 1/2-2lbs. a week. That may not seem much, but it meant a loss of 100lbs. in 16 months. For the last two years I've pretty much maintained at 25-30lbs. from goal and know exercise, rather than food, is the key at this point.
I understand getting fed up with a plan (I took a break from WW for a couple of months during a particularly lengthy plateau and went the Atkins route. The change must have shaken something up inside because I did lose, but I went back to WW because I didn't find Atkins a plan I was comfortable enough with to follow for life).
You've made excellent progress already. Whatever you do, whether it be change of plan or sticking with what's working for you now, good luck!
