Exercise: take once per day and follow directions. Avoid doing it while driving. For best results, do not mix with alcohol or drugs. Some soreness is expected, avoid if pain persists. Take it when you feel up, take it when you feel down as expected results depend on consistency. Ignore the recommendations of the stupid and famous who advise you to push too hard. As with any prescription: use common sense when following any plan. Expect physical, mental and emotional benefits, although results vary. Follow Doctor’s advice and come back the next day.
