Again, my lifestyle has been disturbance. I hadn't studied G Certificate, except Youtube video, And I had drunken liquor for some days. For future, it's no good. So, yesterday, I always stayed at home, and strived to study G Certificate. But I couldn't learn very well. Yesterday, I drank some liquor, so I took cyanamide, the inhibitor of alcohol metabolism today. But will it go well? More thinking, my ideal lifestyle is, "As the brain, I contribute my company, continue to study English, and sometimes go to travel of Japan and various world." I have to remember it, and at least, I have to maintain my health. Recently, my weight has decreased from 94kg to 92.8kg.
