Description:
Regular consumers of caffeine had higher muscle tension after three or more hours of abstinence than low caffeine consumers. This difference was absent after double-blind administration of caffeine citrate or placebo. In a discriminative reaction time test, caffeine treatment improved performance. Among subjects receiving placebo, anxiety was highly correlated with prior caffeine use, suggesting that even a brief abstinence may produce anxiety in the regular user.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, B C -- Lincoln, C A -- Pearce, N W -- Reeb, R -- Vaida, C -- AA 03513/AA/NIAAA NIH HHS/ -- HD 05958/HD/NICHD NIH HHS/ -- NS 11618/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 26;209(4464):1547-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7433978" target="_blank"〉PubMed〈/a〉
