You can try. Three or four o'clock in the afternoon is more suitable for drinking tea. It can help digestion and refresh. It is best not to drink tea too strongly in the evening, and the time is usually around nine o'clock. This can help break down the body's oil, so as not to cause fat accumulation. I didn't know that drinking tea at night would cause insomnia. I have been drinking tea for many years, and I have formed a habit, so drinking tea has no effect on sleep.
