As a relatively new user of hearing aids (three years), and since I’m only mildly hard of hearing (without them, the spoken word is a bit blurry; with them it’s crisp), I don’t feel the need to wear my hearing aids all the time.
Oh, of course at the beginning my audiologist told me to get used to them by putting them on in the morning, not minding them all day long (pretending they’re not there and acting naturally), and taking them off in the evening. Beginners do as they’re told, don’t they? But my days are quite long (6:30 to midnight, I don’t sleep much) and my batteries ran out after 5 to 6 days.
