Ys brthr i agree wd u ....but i persnally experienced a solution fr thz ...... at night b4r sleeping jst think of all gud wrk u have done since morning which must have pleased Allah(SAT) n thn all da lies or mistakes or sins u commited since morning which must have displeased Allah(SAT)......thn jst think which one is heavier eithr gud deeds or bad deeds.... i sure next day u wont feel like repeating those mistakes which we regrtted previous night. Inshallah it helps us to clean rust deposited on our hearts.
