I haven't gone near 151 proof rum since I saw what it did to a college girl. She went into such horrible convulsions that two men and two women could not restrain her violent motions. Somehow we got her into the back of a station wagon and to the emergency room just in time.
From the "spiritual exercises" it is well known that one should proceed to 151 proof level stepwise: starting at 80 proof, one progresses to 100, then to 120 [and one should not forget to fortify one's spirit with flesh, or some other food], and finally to 151. Doing otherwise is akin to an attempt by a soft and not conditioned beginner to run a marathon. Nothing good would come out of either.
