A Vicious Cirycle

"Circle" mostly refers to a physical shape or a group of people. "Cycle" refers to a series of events that keep repeating.

As soon as I got home, I fell asleep despite it only being 7 pm.

If I sitay up until morning, I'd be sleepy in the office.

After I took a shower, I drank tea and relaxed but couldn't geto to sleep.

I tryied to read a book to get myself to sleep but it didn't work.

In the meantimAfter a while, I got sleepy at last but it was 5 am.

"In the meantime" implies that something is happening at the same time. "After a while" shows that the event happened after the first event (in this case, you finally got sleepy after reading a book).

"At last" also isn't necessary because you already have the beginning phrase ("after a while") in the beginning.

But I chose to sleep then and fell asleept.

This sentence sounds a bit repetitive, but if you still want to write this then the correction makes it sounds better.

I drank a very strong cup of coffee.

When I got into the office, I also made a very strong coffee.

Repeating "a very" sounds a bit strange.

Like this I drank 5 cups of strong coffee in the office.

"Like this" doesn't sound right in the beginning of the sentence. I feel like this sentence works well without a transition.

This is a vicious cirycle.😭
