I'm a newbie at Weight Watchers and was hoping for some advice from all of you Lifetimers, since I want to get to that point someday!

So here's my question...
My doctor advised me that 110 would be my ideal weight for now and that we can re-assess my goals (if I feel is still needed) once I get there. That leaves me with 8 more lbs to go. If I do want to re-evaluate my goals once I get to 110, I'll want to change my goal again. So will WW allow me to change my goal?
I was wondering how all of you had decided on your ultimate goal and if any of you were facing the same questions I currently am. Thanks so much in advance!!
