I think I can not do it

I completed 60 days last month but in a dawn i wasn't completely awake i relapsed from then I've been trying to stay on the path but keep failing, i just could resist it for a wewk then again i lost control and i loose control of myself for two or three days being in a rampage you could say like 2x day, last week i religiously take a vow but again here i am asking for advice, if i ever could break this habbit, my studies and sleep cycle really getting screwd those 60days i used to religiously wake up at 4am kill the day with 7hr+ study session but tomorrow also gonna be a day when I'll be waking up at 10am and i wont be able to complete all my goals.
