If you’ve had too much coffee and are left feeling jittery, tired, and over-caffeinated, unfortunately, there’s little you can do in terms of ridding your body of the caffeine. It will metabolize and pass after 6 to 10 hours, though you’ll feel the effects wearing off slowly as time passes. Thankfully, you can still take steps to minimize any discomfort from over-caffeination. For starters, don’t drink or eat any more caffeinated treats and drink lots of water. The fluids will prevent dehydration from caffeine. Also, taking a walk can help relieve any pent-up energy you have. If the coffee has you feeling somewhat anxious, take slow, deep breaths for several minutes to relax your body.
