So I have taken up a course which starts at 9pm in the night and goes upto 12 30 am. 2.5 to 3hrs . It's a online live session. It's a very new subject to me and if there's anything I can do to understand it better is just be more attentive and make a lot of notes. But I'm facing trouble in being attentive through the course. So I feed my baby at around 8 pm put her to sleep and take a shower (to feel fresh ) , have a cup of tea (to control my sleep ) and sit for the course at 9pm. The first 15 20 mins there's general discussion etc and after that the teacher shares the actual ppt and the content starts. So by about 9 45 9 50 PM I find myself vv sleepy. I am just so so exhausted I am dozing off (one day I removed my head phones n went to the bed n slept at 9 42 ,woke up at 10 15 PM, next day I slept on the chair where I sit n take up the course, one day I had to sit on the bed n take up the course and I just couldn't control my sleep I slept off on the bed) . Every such sleep is lasting for 30 mins and this is breaking the flow and once I wake up I see myself totally lost and rest of the course content goes in understanding half information. Note that once I take this small nap I am able to sit through the course completely until 12 30 or 1am . This is not at all helping me. Also the course content is uploaded in the learning website next day at 10 Am and I again sit through, listen and make notes. But this is wasting my time a lot because there is not much time to listen to the content the next day as I have to finish the assignment and submit by evening. In 24 hrs I sleep for 5 to 5.5 hrs, rest of the time goes in looking after my 7m old, feeding, bathing , cooking etc. I cannot sleep much when she sleeps during day time because that's when I get time to do my assignment. If I spend time in watching the video next day I end up having less time for my assignment and I rush through the assignment and submit a shabby work and my mentor gives a comment to resubmit the assignment. So with the new assignment I'm loaded with previous re submissions. What can I do to avoid that sleepy 30 mins during the course? Any tips. I have read that having shower before sleep helps in sleeping better.. So is that 8 pm shower the culprit? I am also finishing my dinner by 7 pm so that I don't feel heavy at 9 pm.
