<p>According to <a href="http://link.springer.com/article/10.1007/s00213-004-2000-x">this review</a> published in Psychopharmacology, it is very much not a myth.</p>

<blockquote>
  <p>The caffeine-withdrawal syndrome has been well characterized and there
  is sufficient empirical evidence to warrant inclusion of caffeine
  withdrawal as a disorder in the DSM and revision of diagnostic
  criteria in the ICD.</p>
</blockquote>

<p>More explicitly (emphasis my own):</p>

<blockquote>
  <p>Of 49 symptom categories identified, the following 10 fulfilled
  validity criteria: headache, fatigue, decreased energy/activeness,
  decreased alertness, drowsiness, decreased contentedness, depressed
  mood, difficulty concentrating, irritability, and foggy/not
  clearheaded. In addition, flu-like symptoms, nausea/vomiting, and
  muscle pain/stiffness were judged likely to represent valid symptom
  categories. In experimental studies, the incidence of headache was 50%
  and the incidence of clinically significant distress or functional
  impairment was 13%. Typically, onset of symptoms occurred 12–24 h
  after abstinence, with peak intensity at 20–51 h, and for a duration
  of 2–9 days. In general, the incidence or severity of symptoms
  increased with increases in daily dose; abstinence from <strong>doses as low
  as 100 mg/day produced symptoms</strong>. Research is reviewed indicating that
  expectancies are not a prime determinant of caffeine withdrawal and
  that avoidance of withdrawal symptoms plays a central role in habitual
  caffeine consumption.</p>
</blockquote>

<p>As for health risks, beyond the symptoms of withdrawal, caffeine has been linked to a number of conditions, such as:</p>

<ul>
<li><a href="http://www.sciencedirect.com/science/article/pii/S0895706102031552">Aortic stiffness among hypertensions patients.</a></li>
<li><a href="http://www.webmd.com/urinary-incontinence-oab/news/20100930/caffeine-and-bladder-problems-linked">Incontinence among women</a></li>
<li><a href="http://europepmc.org/abstract/MED/186223/reload=0;jsessionid=CzWm7s65jDRhoHPFzX4K.10">Insomnia</a></li>
<li><a href="http://www.jstor.org/stable/3702680?seq=1#page_scan_tab_contents">Cardiac Arrest</a></li>
</ul>

<p>So to summarize: Yes, you can be addicted to caffeine. No, it is not a myth. And it seems like you need as little as 100mg a day to be addicted, that is the equivalent of 1.5 espresso shots, according to <a href="http://www.caffeineinformer.com/caffeine-content/espresso">this link.</a>. Prolonged caffeine use can be harmful, moderation is recommended.</p>

honestly, none of these symptoms represents anything that suggests craving. Addition to me is when your body craves for something, like if it was a need. (drink, eat, shag, drink coffee ?) I recognize that quitting coffee is problematic, I personally feel sleepy when I do. But I don't have images of coffee cups floating around my eyes. I don't think about it. Maybe it is addictive to some people, but nothing you mentioned is evidence of this.

I would disagree with your definition of addiction. Collins defines it as "the condition of being abnormally dependent on some habit, esp compulsive dependency on narcotic drugs". The crux here, is **abnormally dependent on some habit**, I also quote my answer "avoidance of withdrawal symptoms plays a central role in habitual caffeine consumption." The failure to keep up the habit results in withdrawal symptoms, the avoidance of these symptoms has been shown to cause habitual consumption. These people are dependent on their habit in order to avoid withdrawal and therefore are addicted.

human habit, tastes, and likes are also a plausible explanation for human interest in coffee,  and the research is by no means conclusive, or unanimous, or even heavily weighted towards the results stated here, which are frankly, paranoid statistical outliers.  This answer is pure bunk.

It's interesting that on a site devoted to coffee, few if any readers think it's not addictive. The consequences of medicalizing/regulating this aspect of contemporary life seem terrible (anyone remember Prohibition?), but the wording of some literature seems to point in that direction.

<p>Depends on how much coffee you consume, the frequency, the duration, as well as the potency of the caffeine..i do know from experience that my body is addicted to caffeine because i get severe headaches when i do not consume coffee (after having my usual dose of triple latte once a day for several months).  The good news is that the headache goes away after two weeks of no caffeine, and lots of ibuprofen. </p>

It's not addictive for most people, and (see my answer below) I question whether the term 'addiction' really makes sense in this context. So when the OP says he has some of the symptoms (aortic stiffness?) in Nick Udell's answer, I wonder if he is looking for a particular answer.
