When do you cut off caffeine?

I don't really worry myself since caffeine doesn't seem to affect me at all lol. I'm drinking caffeine right now at almost midnight and I am sure I will sleep just fine

I do not drink caffeinated beverages, but in the morning I need my coffee. The last cup of coffee is soon after lunch, but no more than 3 cups of coffee per day.

I can consume anything, but I also need to limit the oil I ingest.

I drink it anytime of the day. My sleep is not affected by caffeine

Nope. I will drink caffiene any time, anywhere. In a house with a mouse. LOL. I've been known to drink a Alani when I wake up in the middle of the night.

Usually I stop around 2 in the afternoon, anything after that and I'm up half the night. Then it's just water or decaf tea for me. Funny that caffeine doesn't keep you awake, that must be nice.

I don't have a need for caffeine. Even when I barely sleep the night before, I don't instinctively grab something with caffeine. Not even my green tea. I only drink green tea when I have had too much to eat to help me aid with my digestion and it's not everyday. I could stay awake without caffeine.

I drink water when it is hot outside and I feel kind of weak from the humidity.

Whether or not I drink caffeine doesn't seem to matter. If I can sleep, I sleep...I was brought up with coffee on every table for breakfast, lunch, and dinner. If you were home, you drank coffee. It would take me a LOT of coffee/caffeine to actually keep me awake if I really want to sleep.
