I hear ya on the intense boredom. Since holiday break, I've gone stir crazy.
First and foremost, Congrats on 20 days!!! That's awesome. I'm on day 2 so seeing someone manage double digits is motivating.
As for the skills you feel that you lost....
Perhaps it's the whole transition of sobriety that is affecting your motivation and creativity. Don't be hard on yourself. I'm positive that your skills will return. Give it some time. You are undergoing tremendous changes right now and things are going to seem screwy for a little bit.
Take care, and congrats again!!
