I need to help a family member in need, we just found out he has cancer. Really a good guy.....anyway , they asked us for some medicine. I have access to two or three. In general, would what you suggest ? Being that he isn't a smoker at all, I was looking for something not to strong...I also can get the old stand-by commercial. It's looks a little greener then usual. I'm not rolling in the doe, but want to help. ANY info on this is much appriciated. Also, how to dose for him to help his appetite after treatments.....thanks
