That's pretty much how it works; the get the rush when your body starts using the sugar, but you feel tired when there's still a load of insulin that's already been released, and no sugar to use. The only effective difference between sugar and caffeine is that caffeine has a tolerance component (whereas sugar doesn't), and isn't broken down by insulin.

I like caffeine, but after my early high school career, four cans of Mountain Dew a day was not good for anything other than flipping out. Life in general has improved ever since I started drinking only water.

The only highs I get are from trolling and pretty girls. Sometimes, I'll combine the two for 2+2=5 action.
