Day Two

I am having major coffee withdrawal today. I have not been able to shake this groggy feeling all day and the muscles in my neck and shoulders are so painful. No headache yet.

The most frequent symptom associated with caffeine withdrawal is moderate to severe headache. This can occur between 12 and 24 hours after last intake of caffeine. It usually lasts for one to two days, though some may have a headache for longer.

Others experiencing caffeine withdrawal may feel depressed and some feel sleepy. Some people may experience significant mood instability, which may be helped by prescribed medications. People may also have difficulty concentrating. Some undergoing caffeine withdrawal can have flu-like symptoms that include nausea or vomiting, and muscle pain or stiffness.
Generally the symptoms of caffeine withdrawal continue from two to nine days after one’s last intake of caffeine.
Most people will not feel the effects of caffeine withdrawal three to four days after stopping caffeine.
