I'm in a similar situation. I'm FI, and can pull the plug now, end of the year, or any time after. I'm putting all the salary and bonus money into a cash account; it's my "extra" money for some fun trips or whatever fun activities I can think up - I'm keeping a mental list.
The first two months of this year I was having a terrible time just being at work, and felt depressed all the time because I thought I should be able to walk out the door. I was running numbers all the time, talking to financial planners, watching the portfolio, etc.
At some point, I decided it would be better to try to get into the work the best I could while I'm here instead of thinking about escaping all the time; a work version of "Love the One Your With". I'm finding this is working a lot better for me. Days go by a lot faster, and I sleep better at night.
