How long have you prayed tahajjud before seeing your dua answered?

Hey everyone, I've been praying tahajjud consistently for a while now, and honestly, it's been a journey. I've heard lots of amazing stories where people's duas got answered almost right away. But for me, it's been several months, and I still haven't seen any of my duas come to life. I'm also doing istighfar and reading more Quran, so I know I'm getting rewarded, Alhamdulillah. But sometimes it's tough to keep going when you don't see any changes. Anyone else feeling this way?
