How do you get your groove back?

I went into the studio today, after taking about 3 weeks off. The space was still set up for the big craft fair I'd participated in, complete with a plastic Christmas tree and decorations. I immediately set to the task of breaking the holiday stuff down and rearranging the furniture back to it's functional position. After about a half hour, I was finished and ready to get to work. I looked around me, and immediately, my mind went blank! I had no idea what I should do. Should I paint? Should I draw? Should I check into social media? Should I prep my marbling tank? I was paralyzed by the options! I've spent the last week DYING to get back to work, and once I'm there and ready...nothing. Talk about a buzz kill. 

            My "happy to be back at work" smile - before the "oh sh!t, what do I do" feeling set in.

This isn't the first time I've had artist's block. It seems to happen each time I return from a break, and it lasts longer than I'd like. I've found that it helps me to sit and doodle for a day or two. It clears the cobwebs, and helps me flex my creative muscles a bit, until I'm ready to take on the heavy stuff. 

How do you handle getting back into the flow of work after a long break?
