I've been doing WW for just over a year and like you plan, I rarely ate my weekly points or activity points and lost weight week after week. Now as I get closer to goal it has sloooooowed considerably! I work out daily and my 26 points seem like so little and now, eating some of my weeklies seems to keep me at the same weight or I see a little gain. So maybe if I'd eaten them a bit more often, I wouldn't feel so stuck.
I guess just go by how you feel- if you feel satisfied and not deprived by not eating weeklies/act points then by all means- go for it!
But, the few times when I did have that pizza or slice of birthday cake- and tracked them, staying within wp's and ap's- I did still show a loss. Just don't deprive yourself!

It sounds like you're off to a great start!
