Hello and welcome to the forum.. Your body can do it for awhile.. Your liver and kidneys cannot.. also the effect they have on our life and loved ones can be devastating.. I guess the answer to how long can your body stand them.. till you can not go on any further with them running your life.. as to why we get energy.. I do not know but it is a deceiving kind of energy.. as it winds your mind it steals your health and emotions leaving a shell of need.. need for more drug and no room for much else.. I hope you find it in yourself to get back to your own natural energy as we retain and feel this way.. also the Freedom is liberating and a Natural High I never expected.. I wish you well.. lesa
