Dont worry!! it is all part of the flush. just rest - drink lots of water and in two weeks time do another one. dont eat too heavy yet - though it is tempting - just eat more vegetables if you can. usually when your heart pounds like that - it is coping with a stuck stone... at least it is moving forward. if you tell your doctor - they will just look at you blankly - think you are a hypochondriac and sendyou home anyway. good luck
