Well, if you absolutely must continue your burnout, then don't take vacation. You will spend it dreading the return and it will make you miserable. Try and rationalize away all the concerns about the meaningfulness of what you do. Make sure you are not operating on power saver during the day and give it all you got! Also give it all you got in after work hours and make sure you get some positive emotions out of it regularly. Wake up well rested in mornings with proper sleep habits. Adjust your position in a way that situations that cause strong negative emotions are not your concern.
