Good Morning!

Prophet Muhammad (sal Allahu alaihi wa sallam) said, "When one of you sleeps, the Shaitan ties three knots at the back of his head and says for each knot: have a long night, so slumber. When you wake up and mention Allah, one of these knots is untied. When you perform ablution, another knot is untied; and when you establish prayer, all of the knots are untied and you become alert and pleasant. Otherwise, you become wicked hearted and lazy. [Sahih Bukhari]

So if you want to have a really good day, its not coffee that will keep you alert or antidepressants that will keep you in a good mood. What you need to do is wake up, take Allah's name, do wudhu and pray before morning arrives. Have a great day!
