ne-mu-i, three beats — a flat "neh," an unrounded u, and a separate final i.
nemui
Three units, cut to the same size, with a crest in the middle. The u-to-i transition at the end is subtle because both are high vowels — the way to keep the count honest is to make the u genuinely back and unrounded so it contrasts audibly with the front i.

朝はいつも眠いです has いつも (i-tsu-mo) with its affricate and 朝 (a-sa) with two identical vowels. So the sentence gives you a matched vowel pair, an affricate and then an adjective ending in two vowels that mustn't merge.
"ne-MOO-ee" rounds and stresses the middle vowel and stretches the final one. Spread the lips, level the beats, and clip the closing i. Learners also diphthongise the opening e into "nay," which is a separate error and just as audible.
