What can be mixed with it.?

I have a friend that's ttc...ok so I told her to go out and buy some geritol tonic and she did. She says the taste is horrible but she wants a baby...so shed willing to try any and everything to get the ball rolling..she has one child that is 5 and she wants another one. Anywhoo...what can she mix with the geritol tonic to ease the taste of it. Has anyone ever tried it?
