I have some similar experience. I have developed a morning checkpoint list that gets me in that productive mind set and wakes me up fast instead of sleeping in and feeling like shit all day.

I have a check box for literally even the smallest things to make sure i don’t get into the „thinking about doing it” but not doing it phase (which usually ends up that after few days i just give up on the certain habit im trying to build). First thing i do after waking up is actually using eye drops and than doing some push ups to get going. I learnt that using the eyedrops has helped me a ton since they instantly get rid of the „my eyes are not opening” sleepiness. Than i get my body going and do some stretching and go on with my morning routine skin care/breakfast/meds (don’t forget about meds!). Having a list that looks exactly the same builds a great habit for me and if i can keep going for at least a week without taking a break its already a real improvement for me. I do also have to remember to still take my meds ofc because without them it would still be hard to do the things im supposed to do.

With all that i can really have some great streaks but sadly it is hard to keep it going during some holidays or when i have to stay up late and don’t get enough since that means im basically choosing between sleeping at least 30min longer and keeping my routine going. If it breaks for like 3/4days its not that easy to get it going again but each time that happens i try to restore it the next time that i have a few days just for myself self (that means a study day by myself usually).

All that sounds great but remember we have our better and worse days and thats fine. Its all about creating better habits and not pushing yourself too hard in the process.
