I am so glad to see you are planning on being mindful and patient with this recovery.
I found out new shoes were a must for new hips as the old ones likely bear a bad gait pattern.
Shorter walks several times per day versus longer walks were more helpful and I concentrated on proper heel to toe walking.
(Apparently, I had become a "toe walker" after some years of trying to relieve pressure on my lower back due to bad hips)
I am so grateful to have my mobility and life back after THR.
I won't depress you with how long it took before I got a full comfortable night's sleep

but I DID have double the trouble with both done at once.
Power naps were my go to for the first months.
Onward and upward hippy pal.
