Hey Kate!
I love C25K, and so do many others here - we usually have at least one thread of folks that are working their way through the program going, so look around.
For me, after 8pm snacking was pretty much essential. So instead of trying to change my fundamental nature, I plan for an evening snack and work it into my calories. I firmly believe that you have to tweak your plan to work with you, so talk to your dietician about ways you can do that.
Anyway, I'm so glad you've joined us, and can't wait to get to know you better. Jump on in and get to posting!
