Coffee supposedly has some postive things in it, so I would say the coffee is better.
Caffeine more than anything makes people feel alert, but the down side is as we withdraw it makes us sleepy. Keeping a constant level of caffeine usually does not reduce the amount of hours someone actually sleeps once addicted, that’s why people deny being addicted. They say, “I can go to sleep right after drinking a coke.” But, miss your caffeine fix and you will feel it hard. Sleepy, headache, I even look and feel a little under the weather. People ask me if am ok when I first stop drinking caffeine. I had stopped for many many years, but as I have mentioned on other Q’s, I have cheated a lot the last few years. Anyway, I recommend cutting back a little, you might feel better overall after a week or so. To feel a bad crash, with full blown headache and misery, you would need to skip your normal caffeine time and then wait another 6–10 hours probably.
