I agree that every day is too much! I always give myself weekends off :) But yeah, I think the main thing is to find your own pace that you can keep up and not feel like your creativity is being wrung out of you until there is no more left.

Writing things down physically is a great idea. Not only does it slow the writing down enough so your brain can keep up (a problem I have with typing) but you also have a good excuse to buy some really nice notebooks :)
