Answer
The exact relationship between caffeine and depression isn't clear. There's no evidence that caffeine — a mild stimulant — causes depression. However, some people are more sensitive to the effects of caffeine than are others. In such individuals, caffeine may worsen existing depression. How or why this occurs isn't clear. But several theories exist.
- Although caffeine initially gives you a "lift," it may later have the opposite effect as the effects of the caffeine wear off.
- Caffeine can make it more difficult to fall asleep and stay asleep. A lack of sleep can worsen depression.
- Caffeine appears to have some effect on blood sugar, especially in people with diabetes. Fluctuations in blood sugar can be associated with mood changes.
If you have depression, you may consider limiting or avoiding caffeine to see if it helps improve your mood. However, caffeine can be habit-forming. So an abrupt decrease in caffeine can cause withdrawal symptoms, such as headaches, fatigue, irritability and nervousness. To lessen these withdrawal effects, gradually reduce the amount of caffeine you consume. For example, drink one fewer can of caffeinated soda or one fewer cup of caffeinated coffee a day.

Interesting, thanks for posting!
That is interesting. Although I rarely drink coffee, I do drink a lot of diet soft drinks which contain caffeine. I will have to think about this, as I not only suffer from depression, but also diabetes.
That is so weird that you posted about caffeine. I was just starting to quit drinking so much coffee throughout the day. I drink it all day long and I noticed I was extremely nervous. I am going to try and drink only 1 strong cup a day. I can see how it does give you mood fluctuations because it initially gives you a lift and then you go back down when it wears off. I get the most horrible headaches when I completely stop drinking any caffeine.
That might be a good idea, dan and red. I haven't had coffee for a while before yesterday, and I thought I was doing fine. Then yesterday, all of sudden, I was very nervous again for no reason.
I'm feeling better today with no coffee in the morning.
