When I was still making my research study I also tend not to sleep, not only in the whole night, but I tend to sleep for the whole couple of days. Many of my friends and relatives got mad at me because of that, according to them I might finish my studies but it also may finish me, our health was more important to us and needed to care of. I think its better to always prioritize our health.

Do prioritize your health, we may use all the money they earn for treating ourselves, its just useless if that will happen
