I was wondering whether this would help bring some lucidity.

I was thinking I would go to sleep and wake up 6 hours later, same as a WBTB but I would have some math problems on the desk. I'd get up, and do about 40 math problems (10 addition, 10 subtraction, 10 multiplication, and 10 division.) Afterwards I would go right back to sleep. Whole thing shouldn't take more than 15 minutes.

The point would be to awaken the logical side of the brain so when I return to sleep I would have more awareness and would become lucid alot easier. What do you guys think?
