My friend Kevin had started waking up early and decided that he was going to do it completely natural so he quit drinking coffee. This is similar to everyone who never works out and then decide he is going to run a marathon the next day.
It didn't work out for Kevin. He was miserable after a couple of day and decided to give up woke up early and went back to drinking coffee.
Personally, I had to drink a ton of coffee when I first started waking up early. I've been able to cut them back dramatically but it's what I needed readjust my internal clock early on. Nowadays I really don't need any caffeine (I usually just drink a cup of green tea in the morning) but I want to share a reality of what I have experienced.
