Need someone explain the meaning of a sentence 調子に乗るのも、いい加減にィ…… which got cut-off near the end by the character


**There's a sentence which I'm not sure about its meaning , hope someone can
explain to me. 調子に乗るのも、いい加減に... (the character stopped near the end of the
sentence, so it's hard for my JP level. I can only guess the meaning : "Even
if you're over-excited, there's a limit...")**

Context: MC has been turned into a kid due to an app from his smartphone
(previously there's a sentence refers to Conan by the author ^^) and now he's
acting like a baby, trying to demand his classmate to let him drink her breast
milk (the girl is also a bro-con but she doesn't know about it)

アプリの効果で母性本能を極限にまで引き上げられているので、小さくなった俺に甘えられるのがたまらないようだ。

A (the MC's classmate)「あっく、あッ、あぁッ。強くっ、吸い過ぎだ……！
ハァハァッ、ちょっ、**調子に乗るのも、いい加減にィ……**くうぅん！」

口では拒絶をするものの、A はまったく抵抗しなかった。




The sentence has しなさい/しろ omitted. That is, in full, it is 調子に乗るのもいい加減にしなさい.

Xもいい加減にしなさい is more or less a fixed pattern meaning 'Be moderate in X'. See
[this question](https://japanese.stackexchange.com/q/97336/45489) for details.

So the sentence literally means 'Be moderate as regards 調子に乗る', which means
something like 'Don't go too far'.

調子に乗る in general means to have too much confidence; in this case, confidence
in making advance to the MC.
