I was a heavy coffee drinker most of my life and had to stop cold turkey and did so for a month due to GI issues. Had a headache the first days, but was fine otherwise.

Now I just do half caf and have two cups a day and found a nice balance of not being too dependent on the caffeine.

More than the caffeine I love the taste of good coffee, so I can live with the reduced caffeine.

Not everyone has extreme withdrawal from stopping caffeine.
