After the market is bad, the quality of sleep begins to be surprisingly good, and I don't know if there are other friends who feel the same way. After returning from Jeju Island, I have been able to sleep for 10 hours every night recently, I am not sleepy during the day, my skin is better, and I don't need to drink 2 cups of coffee a day to refresh myself. It may be to make up for the drowsiness I owed for the past six months, and if I continue to endure, I feel like everyone is going to do it.
