I did the same, just the Gym came after work and it was home "Gym". I can't work if I'm physically tired. The same thing with coffee. It doesn't help me at all

I did the same, just the Gym came after work and it was home "Gym". I can't work if I'm physically tired. The same thing with coffee. It doesn't help me at all. If I'm sleepy, I sleep. You can not win fighting your body just like you can not win fighting nature.
