Adapting to the wrong schedule(Day 6 and 7)

This week I've been getting at least 2 hours than I used to get but now I'm getting used to that, but the plan is only sleep 3 hours but have been living on 5-7 hours. The effects from the sleep deprivation are apparent as the walls looking wavy and seeing big patches of brightness are the norm. This increase in time however has allowed me to take back up yoga and boxing, and has allowed me to start leaning piano and violin and the next endeavors are Spanish and Japanese(but not quite yet).
