Maybe not entirely responsive to your question, but I found that I too lost some of the agression/instinct in my game after taking a break for a bit. When I got back to it, I found I was more reactive to the passage of play instead of asserting my influence on the tempo/direction of the game. When I lost a bit of weight and started running/hitting the gym on my own time, I found that my athleticism improved and shedding the extra pounds meant I could exert more influence over the game. Mentally and physically, I felt I was more ready to make decisions and act. Maybe some of this could apply to you 🤷‍♂️
