I've never found those energy drinks work very well - their effect seems more side effect of feeling sickly than actually waking me up. Coffee by comparison has a wake/sick ratio like this: first cup 99/1, second 60/40, third and up 1/99.
I experience quite the same thing: it's the same story with other forms of drug dependence, a misfortune I understand you've largely been able to avoid.
