I've been quitting caffeine completely. It's my third day, and I feel very tired. Please pray that God will give me energy, vigor and focus. I need to be able to focus on homework. Pray that I'll be able to do my homework very well, and study well for the test coming up. Also, pray for energy and focus this next week. Pray that God will lift my spirits and give me joy, because one of the symptoms of withdrawal is feeling blue.
