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.
Timeline can vary. Most people suggest that the brunt of the physical symptoms such as bad headaches and constipation will go away within the first 48 hours of withdrawal. In other words, once a couple days have passed since youâve ingested your last dose of caffeine, most of the physical symptoms should subside.
