Welcome to NeuroTalk. I'm sorry you have to deal with PCS...It's really tough, I know.
When I saw that you asked how to fill your days...it reminded me of an old thread and a response by Mark from awhile back. Here's the link to that thread...Read the first reply that was done by Mark. He laid down some pretty good rules, guidelines and a decent schedule for those recovering from a head injury....Check it out:

I wish you the best of luck in your recovery.
