✔ 最佳答案
If you don't want to use "sleepy" to describe you are ready or inclined to sleep, you may use drowsy, languid or soporific.
我有一點眼訓 :
You may write
I am a little bit sleepy/drowsy/languid/soporific.
You may say
I am kinda sleepy/drowsy/languid/soporific.
P.S If you are sleepy, you yawn loudly.
