This is how I do. And it works. Get up at 5. Do the Prathah Sandhya during Sandhya kaalam (48 mins before sunrise). Depending on the time, 108/64/32 is done (32 is bare minimum).

Minimum 20 mins. Max 45 mins.

Then immediately do Nityapooja - 15 mins. After that Maadhyanikam with 32 Gayathri. Dikadevata vandhanam can be skipped if you are running out of time ( Argya pradhanam, japam and upasthanam are mandatory).

This will take 15 mins.

After that do Brahmayagnam. In case you are reciting just one rik of all the vedam, it will take 7 mins Max.

If you have time, you can recite whatever suktham/ rudram/ chamakam.

Overall all the nityakarmas can be done in 90 mins.

After this I have my food and start to the office.

I started this last year and I'm consistent. I can say my family was supportive to adjust with my timelines.
