hHow was abusy a day it was! i I had to renew all of the products from 10 a:m to 5 p:m.* (?)
i I felt very tired and I had a headache. tThen i I had dinner and used I had a drinks which i love and after that, i I fell asleep around 45 minutes later. sSo, all of the tiredness was had disappeared. wWhat was needed was to be comportable comfortable!

*Generally speaking, physical products are not something "renewed", but I don't understand the intent of this sentence, so I can't correct it.

- The first letter of the word in every sentence needs to be capitalized. Otherwise, it reads as though you are texting.

- "I" (personal pronoun) is always capitalized.
