It is usual for Satan to do this after any good form of worship as you are slowly going away from his traps! This is why he is trying his best to give you such whispers and doubts to confuse you and get you out of this state of righteousness!

You have to assess your daily life, and try to eliminate those things that are not inviting you to earn the love of Allah. These can be bad company, time wasting, music, watching things that are haraam, free mixing or any other thing that earns the displeasure of Allah.
