How to get out of feeling sleepy

Since yeaterday, my body has been lack of sleep and it is terrible. This morning I got up later than other days and I rushed to workplace, fortunately, near my school and I have to take only 5 minutes to get there.
This morning I helped to train a new colleage about SEO and how to get quality backlinks from forums. I hope she can bring new positive outcomes for our company. She has good writing skill. Oh my god, it reminds me to write my mid-term essay because I will have to submit on Friday. oh my god, so stress.
Anyway, work hard play hard. I will try all my best. yeah.

One more thing, my colleage is doing Seo work for our Puma.
My keywords "giày thể thao nam" and "giày thể thao nữ" are going down and I don't know why. Maybe it takes time before a good result.
