I start slowly, only with one espresso per day, and then gradually move back up until I hit the 5 cups a day again Sometimes it's not the substance itself, but the amount; have you tried differing amounts, or limiting to only certain times of day? What you describe sounds like a roller coaster to me (albeit not as severe as some I've seen). EDIT: My personal story: used to drink tons of coffee in hight school; had heart palpitations, quit; used to drink tons of Dr. Pepper through college; decided to quit due to sugar and phosphoric acid; used to drink tons of tea late in college and after; stopped when I stopped working from home. Nowadays, it's one cup (perhaps 16 floz at most) of coffee and one cup of tea per day, always before noon - it has to be fresh ground coffee and good loose tea, though. Has health benefits and doesn't make me jittery, can quit or take a hiatus any time I want, or double down on a slow day. Moderation, with the occasional variation.
