I cut out caffeine about a month ago. Before that I drank a cup of coffee in the morning, and a couple cans of soda or iced tea during the day. Not a lot, but enough to make me jittery.

Another nasty effect of drinking lots of caffeine is that your body develops a tolerance to it, so it takes more and more to give you the same jolt of stimulation. So by the time you use enough to wake up, you've already consumed enough to be jittery. One of the benefits of giving up caffeine is that if you really need to wake up, a single cup will send you soaring again.
Caffeine also has a metabolic half-life of about four hours. This means that four hours after drinking caffeine, you still have half the amount that you consumed in your bloodstream, long after the jolt of energy has gone away. So if a person drinks caffiene throughout the day, it accumulates, and if you drink it even a few hours before bedtime, it may affect your ability to fall asleep.
Your weight loss probably had a lot more to do with sugar intake than caffeine. Coke has tons of sugar in it, and of course chocolate bars do too. Eating that much sugar, your blood sugar probably fluctuated like crazy, and caffeine helps to destabilizes blood sugar too. Let me guess, you felt inexplicably sleepy, so you drank caffeine, and then felt jitty and edgy but fatigued at the same time.Knightfall1972 said:I use to drink 3 litres of Coca-cola a day, as well as anywhere to 4 to 6 chocolate bars. That's a lot of caffeine... and it affected me in ways I didn't even realize until I gave up cola. I felt better and dropped 30+ lbs easy.
