It works better for me than sedatives & with the added benefit that it is an appetite stimulant. You can not get a license to grow unless you are terminal (physically) or your oncologist will prescribe, i.e. you need to have cancer. I would have died of anorexia in my early 20s without it I think. They say it is no good for schizophrenics, but my son is one, & it is one of the more reliable ways of calming him down when he gets violent.
