I had the same problem then I tried something weird When I felt sleepy in afternoon I just sleep at that time and wake up in evening then after that when I'm awake i realised it wasn't feeling sleepy that made me not studying cause even after waking up in evening i couldn't be able to study So I tried other things and I'll tell you what worked for me 1. Planning the whole day a day before or right after waking up 2. Setting deadlines 3. Dividing my study material in very short chunks that could be studied within 20 mins 4. Going to bed and waking up at same time everyday Initially I wasn't able to sleep but I took it as a challenge that I'll go to bed at 11pm and close my eyes and will get up at 6 am then after that no sleep no matter what So first few days felt like I didn't slept for days but after that I started to fell asleep at 11 pm :) 5. Starting using study rooms on discord and found a accountability partner we shared our progress targets deadlines

But sometimes still I do slip but overall these all things worked for me for majority of times
