Us in the Philippines although our weather is majorly tropical and warm, no I mean hot. VERY HOT like our country is sitting next to the sun. And yet Filipinos are huge consumers of Coffee. Yes, you will see Filipinos complaining how hot the weather is while sipping a hot cup of coffee all throughout the day.

A few days is all it takes to regain caffeine sensitivity? So, would going caffeine free on the weekends be a good idea to keep sensitivity up and keep the health benefits of caffeine going?

I don't know about other people but it makes no difference in my body if I am feeling sleepy. Even if you give my a ton of caffeine. That's why I prefer marijuana.
