I feel this way too, that I tend to not meditate regularly, and I sort of feel like I do this on purpose so that I do not make too much progress all at once. This is not necessarily a purposeful choice that I make, but I feel like my understanding has grown so much in such a short period of time, that my body and my mind need time to process and assimilate all of the changes that are taking place.
I just kind of go with my feeling, when I feel like meditating, I meditate. My main feeling lately is that I want to be surrounded by nature all the time. I want to be at one with the earth (I never thought I would hear myself say this).
