Cymbalta is used to treat major depressive disorder and general anxiety disorder. It is also used to treat a chronic pain disorder called fibromyalgia, and to treat pain caused by nerve damage in people with diabetes (diabetic neuropathy).
Caffeine-withdrawal headaches can last up to 48 hours and can be as intense as a migraine headache. Withdrawal symptoms can begin 12 to 24 hours after the last cup of coffee and can last up to 1 week. These symptoms can include lethargy, extreme nervousness, irritability, sweating, headaches and shakiness.
However, the body is considered no longer addicted to caffeine after nine days. Continued symptoms should be checked by a doctor, as they might indicate other conditions. Most people will not feel the effects of withdrawal three to four days after stopping caffeine. So, although caffeine is addictive, it is actually generally a far easier substance to break addiction from. This is good news for those people who must stop using caffeine as per a doctorâs recommendations.
