I often end up almost entirely stopping coffee as soon as a term ends. Last time I did, I also forced myself to go to bed earlier and do some work at home before leaving for work. It worked for quite a while but as the term progressed and work from both job and university piled up, I started to not have time to follow this strict schedule and to drink more and more coffee. It's very difficult when your schedule is tight, but I believe it's better to stick to way nevertheless. Tomorrow, I'm starting this schedule again. Keep going on yours!
