بسم الله الرحمن الرحيم
Go to bed early after Isha. Go to bed with the intention that you will have to get up in each condition whether your heart is not ready and think that whoever misses his one salah is as his family and wealth is looted. If possible, ask your namazi neighbour that he awakens you in the morning for salah or you sleep by setting alarm so that you get up on time.
Allah knows Best!
