Hunger Rating During a weight loss study each of nine subjects was
given either the active drug m-chlorophenylpiperazine (mCPP) for two
weeks and then a placebo for another two weeks, or else was given the
placebo for the first two weeks and then mCPP for the second two
weeks. As part of the study the subjects were asked to rate how hungry
they were at the end of each two-week period.
