Can I say,

Yesterday night, John was not feeling well. He had a headache and a fever. He started vomiting in the toilet.

Last Thursday night, John felt unwell. He had a headache and a fever. He started vomiting for half an hour.

Last night, John was unwell. He started vomiting continuously throughout the night.

I see no problem other than that "Yesterday night' should be 'last night'... and that John is a bit silly for not visiting a doctor!

Thanks. I thought " was not feeling well" is incorrect. Thanks.
