We are all different I would never tell my husband that he has to do it. I would just do it an extra time myself like Humaworm suggests. It is simple to do.
My husband is not interested in doing all the things I do, but he is happy for me that I feel so well. It is hard to see all the things he does, which are in my eyes not healthy.
Alternative medicine is such a personal view. Look around you may be 1 out of 100 people might be interested, if that many. If you see even the debates on many forums, even here we don't agree with everything.
You can always hope when you yourself get better may be he might become interested.
So many people have seen my general improvement in health and even if I tell them I started with cleaning my liver and got off all my (6) prescription drugs noone askes how did you do it!!!!!!????
