Weekly points are something that I think every Weight Watchers uses in a different manner. Some ration them out for each day and some save them for events, etc. I don't think anyone can use them incorrectly and honestly, I think you need to use them for what works best for you. That being said, I always, always try to save my weeklies for the weekends. And by weekends, I mean Friday night - Sunday Morning.
I am Twenty Nine and Single and I like to go out and have some fun on the weekends or go up to my cabin and be able to overindulge. 90% of the time, I can stay within in my daily points allowance Sunday - Thursday. I try to eliminate dinners out and happy hours as best as I can during the week. And if all else fails, I will mix in an extra workout or something to have some additional activity points so that I can indulge a little during the week.
Some may find that blowing weeklies on cocktails, beer and wine is a waste of points... But in the end, they are my weeklies and I can do whatever I want to with them.
That is what the beauty of Weight Watchers is... you aren't limited to anything and they don't restrict anything... You learn portion control and moderation. Most the time it works for me and I am thankful I have the flexibility. Because sometimes.... I just need a bottle.....errrrr.....Glass of wine!
