Hey! I'm a tax practitioner, and I feel you! It's really hard with all the stress.
All I can say is, plan plan plan! Make sure you get your foods lined up, and make sure you get your exercise in.
And if you can't manage that, maybe you need to rethink how you're working! Just because your clients are in a rush, doesn't mean you have to be. I know, that's hard sometimes, but I've found it's true.
I recently attended a tax workshop for CPEs, and I was the slimmest person there, except for one other woman... I knew that tax season took a toll, but wow.
