This "early-going-to-bed" and the fact that you feel tired and can't get enough sleep can also be considered as the so called "spring fatigue" or as we call it "пролетна умора". Don't forget the change of time for day-light saving and the lack of vitamins and sun during winter. And winter was especially long and severe this year. :) Hope everything went OK today at the hospital and you'll get better soon! At least spring break is on it's way!
