I quit cold turkey because of sleep problem I was having and stayed off it for about a month while I was isolating possible causes. I don't really think cold turkey vs gradual cutoff would have made a difference for me. The biggest thing that helped was having something else to sip on (decaf tea + sparkling water in my case). The lack of caffeine was really only noticeable for a few days.
