What do I tell family and friends?

I'm going to be starting the hcg protocol as soon as my supply arrives from drugdelivery.ca (hopefully in a week or so) and am very excited!

I'm kind of struggling with what to say to family and friends when they ask me 'how are you doing it?' (Of course, I'm assuming this will work and I will lose fat quickly and people will notice) There is a part of me that is still a little leary about this, and that's after researching and finding virtually no reports of negative side effects.

I can only imagine the reaction I would get if I told anyone I was taking hcg injections to lose weight. They would probably think I had lost my mind, was putting my health at risk, and needed counseling or something...
