There's a thought that needs to be constructed into a sentence, but I am finding it difficult to string the words together. The intended sentence, if I am not mistaken, is comparative in nature.
The muddled thought/idea is as follows:
He behaves the same when he is drunk like he behaves when he is sober.
As you can see, I am not very good at constructing these kind of sentences. If you could please help me find the correct structure for the sentence above, I would really appreciate it.
Further, if possible, could you tell me what this kind of error is called, in grammatical terms? I'd really like to be able to form these type of sentences on my own.
