I love drinking coffee

I don't feel like working today, i wanted to continue my sleep because i slept late last night. I watch tv until 12 midnight . I went to bed after but still i had a difficulty to get a good sleep, maybe because of the cup of coffee after my dinner. The effect of coffee to me is make me awake six to seven hours after drinking. I am trying to avoid coffee except early morning but that evening, our viand was beef steak. I can't really help , i really love drinking coffee and can't avoid myself not to drink very hot coffee after eating any kind of beef recipe.
