I have a similar experience with caffeine. I really enjoy the boost that I get from coffee and chocolate, but then the buzz wears off and I crash, feeling irritable, tense, and on edge. It's the withdrawal effects of the caffeine, and it can go on into the next day (unless, of course, I take in more caffeine, which just repeats the cycle). Some people like us are more sensitive to the effects of caffeine (and alcohol) and are just much better off without it. Better sleep, more even energy and moods throughout the day, etc. I, too, miss the coffee buzz and the social aspects of it, but for those of us that are more sensitive to caffeine, the negatives outweigh the positives.
