Welcome to WW and good luck! As for hints, tips, etc:
Drink LOTS of water!
Wear the same outfit every week to get weighed in.
Go to the meetings - lots of support, hints, tips, recipes
Use your meal tracker, it helps keep you accountable and on plan.
Don't deny yourself something you really like, work it into the plan.
Try looking for Weight Watcher recipes - I've tried a lot of new dishes, eaten well and still lost weight.
Switch to whole grains - whole wheat bread, whole wheat pasta, brown rice, etc. (not always less points, but better fiber for you)
If you go off, have a bad day, get right back on the next day!
Good foods to keep on hand:
Lofat yogurt
I Can't Believe Its Not Butter spray
Fresh veggies (carrots, broccoli, cauliflower, etc) and low fat dip for munchie attacks
Salsa (great for adding zest to about anything)
Egg beaters
Low fat popcorn
Fat free sour cream
Sugar free jello
Fat free pudding cups
Also, there is a web site, Dottie's Weight Loss Zone (dwlz.com) that has her personal journey, plus LOTS of recipes and points for food at just about any restaurant you can think of. One of my favorites for lunch is a Wendy's side salad - no dressing (0 points) topped with a small Wendy's chili (3 points).
Good luck and keep us up on how you're doing!
