I totally get the brain rewind thing! I schedule my pages ahead of time, and I feel so weird writing the creator comment based on when it will be posted verses whats happening in the moment.
It's worth it to have the buffer, imo. I take way to long to make each page, and I tend to have weeks where I'm not very productive, and weeks where I'm super productive. Having a patreon helps, tho, since you can post everything early there, you still kinda get that "I posted it!" feeling. But you'll still have to keep track of who has seen what where!
