Hang in there, Yray. It may be difficult but you are doing it every day nonetheless 🙌 Also, I think you could try green tea instead of coffee. It may not be as tasty but the health benefits are higher. I also learned that mini exercises will help too because in moments of inactivity, the heart slows down to a point that your body thinks you are on your way to sleep--hence the sleepy feeling. So for long boring sessions, you may try walking in place or even arm exercises while sitting just to keep heart rate at a steady pace 😊
