Welcome and good luck
WW really works but like everything it takes work.
My top tips are
Plan - if you are able to plan your meals, you will find pointing easier. I don't necessarily mean you work out all the points for the whole day, but if you have a guide to what you're eating then you're less likely to go off plan
Eat your weeklies - I always say eat all your weeklies, and see how your weight loss goes. My personal view is its best to use your weeklies and if you ever have a plateau, you can reduce your weeklies to kick start your weight loss. I have done pro points twice and always lost using the weeklies
Track - another must is write everything down. It's very easy to forget what you've eaten, so if you can, write everything as you go along the day.
Make your meals first choice - with WW its very easy to use your points on unhealthy foods, so I always try to use my points on the meals first before looking at snacks.
There are loads of tips, just one more thing from me. I always think don't bother cheating yourself with your points (massaging the figures lo) your body is a true tracker and knows the truth which will be reflected on the scales. So I always say be honest with yourself, cos you'll get found out ha ha ha
Good luck x
