Oh yeah, when I double-checked my information for the above comment, I also ran across this section, which is kind of wild (Hitler was clean-edge in some disciplines, while not at all in others):

Hitler stopped drinking alcohol around the time he became vegetarian [...] He was a non-smoker for most of his adult life, but smoked heavily in his youth (25 to 40 cigarettes a day); he eventually quit, calling the habit "a waste of money". [...] Hitler began using amphetamine occasionally after 1937 and became addicted to it in late 1942. Speer linked this use of amphetamine to Hitler's increasingly erratic behaviour and inflexible decision-making (for example, rarely allowing military retreats).

Prescribed 90 medications during the war years by his personal physician, Theodor Morell, Hitler took many pills each day for chronic stomach problems and other ailments. He regularly consumed amphetamine, barbiturates, opiates, and cocaine, as well as potassium bromide and atropa belladonna
