I was on the meds for 18 months, and transitioned early on to taking all 3 at bedtime. It was the only way I could tolerate them because the nausea was otherwise debilitating. Please look at some of the other, older discussions on the forum for suggestions on easing any symptoms you may have, with ginger tea or candies, frequent small meals, and probiotics.
Also, please consider seeing an audiologist for a baseline evaluation of your hearing - I saw mine every 3 months (until Covid) to make sure the meds were not accelerating my hearing loss.
