working out and weight watchers???

i work out (a lot) and was wondering what i should do with my activity points. i usually don't take them into account at all...should i?

the problem is i get home late from the gym usually, and i don't want to use my points at 9 or 10 at night

any suggestions?

i guess so...but then what if i don't make it to the gym and i'm hungry when i get home!
