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.
Those who consume the most caffeine, alcohol and sugar, and those who have the highest toxic load, tend to have the most difficulty initially. In any event, symptoms of withdrawal usually disappear after three or four days. It is best to slowly reduce your intake of caffeine and coffee. 1  Make sure you drink at least six to eight glasses of filtered water daily. 2  Instead of coffee in the morning, take some warm water with freshly-squeezed lemon juice.
