What this does not settle

Being clear about the edges of this, because a course is not a mufti.

Whether a voluntary night prayer you have kept for years takes on any further status is a real question with a real discussion behind it, and it is not answered here. Nor is the question of exactly when tiredness reaches the level the concessions describe, or how far a person may reduce or sit for taraweeh in Ramadan when they are driving to work in the morning.

The reports above all point in one direction and the harm prevention principles point the same way. Stating the ruling is still the scholar's job. Take those questions to somebody qualified, once, and then act on the answer rather than collecting more of them.
