I mostly agree with the process the article goes through on curbing caffeine addiction. The withdrawal process is crazy painful and there are better, though longer term processes, to get over caffeine in a manageable way. When I first started freelance/contract dev, I was drinking 2-3 pots of coffee a day. That's 12 cup pots. Burnout and heart issues after around a year and a half forced my change. However, I love the taste of strong, good coffee. Decaf doesn't cut it. I'm not quite a coffee snob, but I sure can appreciate a good cup of quality coffee. I don't drink soda or anything else with caffeine, which arguably helps.<p>Cold turkey for coffee isn't worth it. I've gone through 5 caffeine purges that lasted for 3-6 months of no coffee (the taste... the glorious taste is what pulls me back). If your coffee abuse has been long term, don't bother with cold turkey. The withdrawals make you out like a heroin addict.<p>I also don't recommend going straight to tea. You'll end up drinking a whole lot of tea to equalize the caffeine amount compared to coffee. Start cutting your daily intake in half. Stick to that for 2 weeks. Then cut down again by half for 2 week periods. This helps curb those withdrawals or make them non-existent. Once you're at a cup of coffee a day, stick to that for at least 2 weeks, but I found dragging it out to a month had better long term results on my first successful purge.<p>Now is a good time to switch to tea, but again, discipline to 1 cup a day. Never more. A cup of Earl Grey has roughly half the caffeine of a cup of coffee (depends on brands and how you brew). So, you're still sticking to the halving pattern. Another 2-4 weeks.<p>At this point, you have the habit under control and can maintain this with little discipline (but you still need the discipline 1 cup of coffee or tea daily and no more). If you want to quit, now you're going to go with no caffeine days. 1 day on, 1 day off for 2 weeks. Then 1 day on, 2 days off. Then 1 on, 3 off. At that point, I then can quit. With the 2 week intervals, I run into nearly no withdrawals, just mild cravings. Cravings are way easier to deal with than the withdrawals.<p>I do Lent, so this is why I now have a process to effectively deal with caffeine when the time comes. My caffeine purging experience is a rough 6 year exploratory process, change as needed for your life. I'm at the point where it takes a month and half to kick it and have no withdrawals. The withdrawals are such murder, way worse than fasting.
