Am doing it again!

I have been telling myself not to drink any drinks that contains caffein but duh, here I am again, drinking a tea even if i know that it contains caffein. I know it was so foolish of me to that thinking that it is only me whose going to suffer at the end. But what can I do. I need to drink and water is no where to find. So here I am still wide awake at almost 4 o clock in the morning..my mind is so tired and been telling me to sleep but my eyes wont shut down.i would maybe stay up until morning and will sleep till i felt really really sleepy..
