The study timetable gets ditched way too often
Build your timetable in reverse. By this I mean, place the times and dates in to your schedule when you are NOT going to have time to study. Then, build your timetable around those 'exclusion zones'. In this way, you don't have to stop socialising or de-stressing via other activities. You can still watch your favourite shows and have time every day for other things you love doing.
