I've noticed that something in your body changes when you hit 30. Before I was able to pull all-nighters easily but nowadays I simply cannot. It's 12:45 AM here and I've been up since 9AM and I'm already on the verge of falling asleep no matter what I do. It's something else it's like you fluctuate between awake and sleep and sometimes I even see hallucinations from the side of my eye like shapes moving and shit. I don't have problems with energy during the day but in the evening I'm full kill it's weird.
